Hi everyone, for the past 2 months or so ive been restoring my 1993 dt50mx. upto now i have bare metalled the whole bike and coated it in red oxide, then gloss blacked it, redone the brakes and cables. Then masked of the rims and tyres and painted the hubs and spokes. i rebuilt the wiring loom with new connections. Ive stripped the engine and had the crankshaft rebuilt with a new conrod. Put in new crank bearing and seals, new clutch plates and the rest of the seals replaced. And put it all back together with a new gasket set. I also put a new big bore kit on as that is what i had on last time before the piston melted so wont have to re-jet the carb when i start it u…

Ok chappys i have a yamaha xj 600 1997, i have been tinkering with it and yes i no it is not a sports bike but as with anything i touch i like a little bit more!! it is my first big bike had her for 1 year to date!! but i just had a nice little full stainless jamo system put on and before i get the carbs balanced i thought about getting some direct air filters on the carbs, as in k&n or similar to that, everyone i no says no don't do it!!! but is it really that bad? i mean more air should result in a bit more umphh!!!???? please give me your thoughts oh great one's!!

hi all been a while since iv asked for help but iv managed to get the project going right.... iv given it a test run today and have noticed that at 9000 rpm the engine sort of splutters then kicks in again (like iv changed gear) but its a little rough from 9000 up the plug is reading ok if not a little lean....its a weird problem that i havent come across before so was just wondering if anyone has an answer to why its spluttering? cheers. Paul.

Hi! Coming back to biking after 41 yrs. My last bike was a '52 BSA A10, so the '98 Yamaha XJ600n I've just bought is very exciting! It's a 2 owner, low miles bike that has been taken care of. But of course it has a problem! It starts and runs with great enthusiasm, but gear changing is ruining the riding pleasure. Letting the clutch back in after shifting meets nil revs and of course opening the throttle make this worse - from nil to strong instantly! Hate to think what this is doing to the transmission. First (and most obvious) sign that all is not right is the tickover/idle. It ticks over well, but is 'hunting' all over the place. Just like a leak in the inlet or…

Hi All! First I just wanted to announce to the world that I got my '89 XJ600 back on the road after 10 years storage in someone's garage I just got it MOT'd and rode it a couple of times today. Bike feels good, balanced and comfy. It handles better than I'd expected. There seems to be plenty of power (gears seem very close together..), throttle response is ok, it just sounds a bit rough, a bit lumpy. I cleaned the carbs using solvent and cleared all the passages, especially the jets, but there could be a bit of residue still in there. It is possible the ignition is not at its best either (old HT leads and plugs, though I gapped them). The question …

Hello all I just need to know if anyone has tried putting new "bigger" tyres on their YZF-R125? If so............. What size did you go for? (Standard front: 100/80/17) (Standard rear: 130/70/17) Was there suitable clearance? How much did you pay for them? (supplied and fitted) Where is the cheapest place to order from? Thanks all MarkyMarkR125

Hi all Am looking form a little bit of help and advice. I have a TZR 125 2RK with a mikuni carb fitted. I have cleaned the carb out and set it according to the Haynes manual. When I fitted it back to the bike it was fine untill I had given the bike a run and then the float stuck and it leaked petrol every where from the float chamber overflow. I then tried a second carb that had been removed from a spare frame. This gave me the same problem. If I tap the float chamber then the leak stops but I don't think that both of the carbs are likely to have faulty needle valves. Has anyone else had similar problems and if so could you suggest anything for me to try. Thank…

need help. anyone know what the head bolts on a 77 xs 360 need to be torqued down to?

Hi there all, ive spent this week stripping down my engine on my 2002 dt125 to make a gasket to stop it leaking oil, ive just finished putting the engine back in the bike today got it all wired up and a few kicks later it wouldnt start, i decided to bump it off.. still not going so i took the plug out and it had no spark, firstly i changed the plug, still nothing. i checked the ht lead and its fine, checked all the wires to the stator and they all seem to be fine and have continuity, im just stuck with it now been trying to trace some wires and check them. i have checked the kill switch, the side stand switch. can anyone suggest some other ideas to fix it, urging to be ba…

heres what we got. 1981 Yamaha SR250 with an electrical gremlin that makes me want to punch a baby. heres what its doing. pressing the start button turns the headlight off. when you release the button the headlight goes back on again! Was able to jump the starter solenoid and it would turn over = so i thought the solenoid was bad... replaced the starter solenoid- same thing able to jump the new one= engine turns over. trying to start it normal headlight goes off. im at a true loss of ideas at this point hope someone can shed some light on this thank you so much! -Mark

hey all basically my xvs 250 broke down on my way to work two days ago i was happily riding along when i started to gradually lose power. until it got to the point where i completely lost power. i waited around (AGGGGGGGGGGGES) for the AA and the guy said he is 95% sure that its my solenoid. im new to this but i was under the impression that the solenoid only started the bike? basically my question is, could the solenoid have caused me to gradually lose power and brake down? would rather have a rought idea b4 i buy a new one

hi all , my missues has a SR 125 , and it seems to be slipping out of gear , would this be to the timing ? any info would be great , dont want to spend a load of cash on it cheers fritz

i was fooling around a couple o weeks ago and found a site that gave parts listing that were common to different bikes ie clutch plates fro my xtz were the same as xt 600 blah blah and so on bear ing for this was same as this bike and gave a list of maybe 10 diffedrent bikes that used the same parts but cant find the site for love nor money any body and ideas would be very habndy to have a link on here for it as the russian on is a bit bogey

Hi Everybody, I didn't really wanted to start a new topic, but even running a search, I couldn't find a decent answer to my question... I was wondering if anybody else has a strange noise coming from the engine or not. It is a constant "whistling-grinding" noise and I couldn't identify any corelation to speed, revs or anything else. It starts as I start the bike and continues even when is already warmed in and have some miles behind me. Any ideas where this could come from? Thanks!

any advice would be much appreciated. Ok im going to be purchasing an sr 125 and the seller says the teeth on first gear have slighlty eroded (1st gear rattles) and says its best to start off in second gear. Now im wondering is this worth purchasing? the bike has done 25k and its the 1992 model. Does any one know how much it would cost to recondition the gear box?

Evening guys, I have recently bought a 1991 xj 600 pre div for the commute to work. My question is this, the front brake performance seems quite poor. The bike only has 14000 miles on it and the pads, discs seem good and I don't think there much flex in the hoses. They are twenty years old I guess!! So I need advice on what to do next? I thought the pads may have become contaminated maybe or perhaps I need to overhaul the calipers with new pistons and seals. I've bleed the system so far and cleaned up the calipers and pins.... What is the normal performance for these brakes, mine seem lazy and not as sharp as they should be. has anyone upgraded the calipers?? …

Can anyone confirm the correct amount of fork oil for my dt175mx 1978. It says 148 in the manual is this correct as my forks apear very soft. Ive used the correct oil. may be because im used to the xjr,lol

I have a yamaha ybr 125 2010 model had it for about 7 months now and works great apart from it won't go into 5th gear? I get to four and when I try to flick up it just won't go in? What I shall I do about it I'm not a very mechanical person so does it need to go for a new gear box? Any advice would be much appreciated thanks

Hello everyone, had a bit of a bang on the YBR the other, just some scratches on the bodywork really, yet the needle has fallen off within the dial! I've just been tinkering, the oil is still on my hands! but I just can't seem to get into the actual dial. I don't want to buy a new one as they're not exactly cheap, it doesn't bother me that much as I change by sound but it just looks terrible! If you want to see the dial, it's in the video on my channel http://www.youtube.com/user/curlyblakeybiker Any help would be appreciated Blake
