  1. I've had it since august, Im hoping your wrong about the abuse, but its looking more that way.. I've also heard on a 125 v twin 30k miles can finish an engine. which wasnt what I wanted to hear, but I've also heard the opposite said. If Im lucky I'll find a cheap fix, if not... I have a friend who may part ex his barely used one with mine may be my best bet
  2. Well, the bike is losing power at higher revs. struggles heavily to get passed 40/45, burning oil badly as well. My guess was the rings were shot. So stripped it down with a mechanic (girlfriends dad) Who double checked the rings individually in the barrel, the piston in the barrel and has taken away the head to check the valves are working as they should. What we found was that the ring gaps were a little too big, and the barrel itself had a bit of give in the middle with the piston. The piston itself also had movement on the rod. In other words, it being a 10 year old bike with 36k miles on it, these are likely the original parts that are just worn down. He said the best thing I could do is see how much it costs to replace all the parts, and go from there. If I replaced these then it'd be like a brand new bike effectively. Ofcourse if it really will cost £500 just for one.. and its a v-twin.... I'm sure there must be cheaper parts somewhere.
  3. Also, does anyone know if the 125 XVS shares these parts with another bike? perhaps I can search for them as well
  4. Thanks I checked it out, and they have every part I need... for a staggering £500 for one cylinder! The barrel alone costs £350. The rings £80... is this really the cheapest these parts are? I'm struggling to get anything on dragstar barrels at all but there are some brand new ones on ebay for other yamaha 125's for £50
  5. Hi guys, I'm looking to replace my pistons, piston rings and likely the cylinders as well, I was wondering if anyone had any idea what the exact specs I'm looking for are? Cant seem to find any info for a Dragstar 125 anywhere, obviously dont want to order the wrong parts. If someone has a link to somewhere that sells these things or just the spec I need to search for to get a result come up it would be much appreciated. Any heads up on cost would also be appreciated Cheers
  6. Fixed! took a while of exploring and stripping the bike, pure hope that the petrol wouldnt come out the tank (who would have thought the "on" position is also "off"...) some rather fiddley business around the valve caps because of the tree of metal holding on all the plastic parts but we got there! Smell of petrol is light, throttle is responds bang on and no ticking! spark plugs will need replacing but it works as it should now, starts from cold with any throttle really or choke Only concern is it idles quite high and my idle screw knob is missing wire seems a little seized as well. but high idle should be a concern right? Thanks again for all your advice and help guys! couldnt have got through to the problem without other heads to bounce off.
  7. Had a mate round to have a look, another coming round saturday who had a thought: Valves! The slight noise I mentioned goes with the engine tick over while idling. There is a lack of compression (cant pull off, sluggish throttle, no throttle power with lights on) Strong smell of petrol and choke floods the engine and it can be started from cold without the choke on meaning its running rich. From what we can gather this all seems symptoms of the valves being out of whack. Check plugs again today, may need replacing, were black/brown and one was wet. Hopefully this check on the valves on saturday will provide some results! will keep you guys posted
  8. Ok, a little stumped again >< been following this http://www.electrexworld.co.uk/pdfs/Troubleshooting-3P-PMG-&-RR.pdf The current on the battery seems fine. stands at 12.7 - 13.4V with engine off around 13.6V to 14.4V engine on and idle. no real difference in revving it now. Took the terminal off the Reg/rec and tested the pins in the reg/rec itself follow step 4 of this guide. got readings of around 550's on all of them. According to the guide that means it isnt a reg/rec problem (I would be relieved, given the cost and also the state of the bolts holding it in place...) This guide has further steps to find the problem which Im really not sure I have the ability to do. I wouldnt know where the generator is for one thing. The symptoms today seemed to be intermitent, It idled fine again, throttle was sluggish but picked up after running a while. I noticed that while revving it the neutral light would occasionally get brighter and this usually led to a stutter when revving from idle. An almost stall, and occasionally actually stalling. Turning the full beams on led to no power in the throttle at all. barely moved the revs. Tried to pull away with lights off and it wouldn't have it, just not power in the throttle once in first. Is this guide feeding me crap and this is still defo reg/rec? or is this a bad connection somewhere else. either way I think Im going to need someone to have a look at this.
  9. They do seem to have a good test which I will try on the reg/rec, if I can manage to get to the reg/rec and disconnect like it says. The reg/rec they supply is however more expensive and looks to come with fixed wires, I believe mine has a terminal which can be taken off. Wemoto either don't stock the reg/rec for my bike or its on of the ones listed as a parts number which I've no idea how to wade through to find the correct one. Looks like ebay is actually my best bet. though I think I'll stick with a new part rather than the used one. Also just wanted to thank you guys for your help and advice with this. Its really been my main port of call for help on this problem so cheers for getting me to an actual conclusion rather than helpless and with a dead bike lol Any further help is welcome too
  10. Doesnt have my Bike as one of those it is for. Does that matter? It seems to be my luck these last two weeks that every part for my bike costs double that of ones for the 650's and 1100's This is the 5 I get on eBay, the one you show is there, but its for a 125 YFM rather than Dragstar. there is a chart further down on its page and 125 Dragstar isnt shown. it is also a different shape http://www.ebay.co.u...6.c0.m270.l1313 The only one of a similar price is a used one.
  11. So got me a multimeter. turns out just £6 from Maplin Anyway, readings were fine initially. 12.7V standing, similar while idling, only dipped to 11ish with ignition. Reving gave 13-14V Then it stopped being normal, the idling revs increase, started reading 17's with revs and turning the lights on made it lose power returned to sluggish throttle Im guessing this can be nothing other than reg/rec? which means £60 I dont have plus 4-7 days waiting on it. Anyone find me a better deal i'd be most happy. Gonna look myself as well.
  12. Found it, in a nice inaccessible place... just been to start it up again/find the reg/rec. Started perfectly fine this time. throttle still sluggish to begin with, tested lights under revs and they actually got brighter visibly under revs. I dont have a volt meter and would rather not have to fork out for a reg/rec given they cost quite a bit, hence testing that and reporting back here. Defo some connection problem though as the throttle this time was stuttering and bogging down when revs applied this time, as if a loss of power. Checked tightness of battery connections. tight as I can get them. could be they are dirty? or you guys pretty much 100% its the reg/rec despite the brightness test (only thing Ive got to go on Im afraid) Was a slight noise coming from the area under the oil filler cap (not the filter under the yamaha sign, but the bigger circular part on the left of that) Have checked the oil a few days back and it was defo in the middle of the two points. will check again later. Cant remember which noises are normal from the engine anymore
  13. What am I looking for? If Im honest I have no clue where to look for connection issues, dunno where the earthing is. and I know what the reg/rec looks like but dunno where it is on the bike. How can I tell if the connections on something is bad?
  14. Update: Got the thing started using prime on the fuel cock. Sounded weak though. took a good few tries before it would idle. throttle is reallly sluggish and it misfired a couple of times under revs while idling. checked lights under revs and they dont dim so dont think its reg/rec. Any ideas?
  15. Sparks are also dry. look pretty clean too. Not entirely sure what I'll looking for though.
