Hey guys, Whats the use in posting on general bike forums when theres a dedicated yamaha site, TOP SCORE!! (Glad i found you guys...) ANYWHO... Ive got a DT125 2001 model, everythings hunkydory, or was for a while.... I rode the bike for a few days after i bought it, then one trip i noticed my engine temp was increasing pretty quick, so i stopped and looked, id lost the little rubber bung out of my radiator overflow box under my left rear pannel, and water had splashed out onto my swing arm. Seeing this i thaught a bit of RADWELD radiator cleaner and expensive coolant additive would do the job.... I drained the radiator and did the process of cleaning and putting lov…

Hello,, anyone know if an rd engine would fit without too much improv into a 74 tx500A chasis?

Hi! I have 1993 Xj600S Diversion with a faulty engine. Tomorrow I`m gonna get another engine, from a newer model(1999). These newer models have an oil cooler, but everything else seems to be the same. Can I just ignore it and connest oil cooler hoses together? Earlier models could easily do without it, so would it be a problem in this case? If any answers, thanks a lot!

Hi, I basicly have got this at xmas it's purely for using off road. It does have a MOT etc though. Anyway the front pipe had a massive hole in it, So i bought a new one from ebay just a standard one. And fitted that. I now want to rejet the carb but i have no idea on doing this! People i have spoken to said i should go up a size then it will be better so on. Whats the cost in doing this? Is it a hard job todo? Also i would like to look at derestricting it. If somebody could explain that to me that would be great! It's a 1991 version if thats any use. Thanks Phil

Hello all, I was wondering if there was any one within the club who would be able to give me a date of manufacture from a frame number? The bike is a TZR250r (import) Number: 1KT – 004457 I do hope someone can help me out, as I am trying desperately hard to register the bike. Many thanks Richard

I have a new Midnight Star which has now done 600 miles. I've noticed that when I turn it off and it starts to cool down there is a tiny amount of coolant coming from what looks like a round hole in the crank case. It might be a vent but should it be letting coolant out. Anybody got any ideas?

have just started my race bike after doing engine rebuild. only firing on 3. have tried plug swap and coil swap, these have been eliminated as a fault if i pull plug cap off while engine is running it has no effect on idle or running but other 3 cylinders will stall the engine if i try this. when i pull plag cap off 1 it arcs everywhere and gives me a belt ! other 3 don't do this. bike had been standing since autumn before rebuild. gave battery bit of a charge. do they need a certain voltage to run the ignition system properly ? i think it's 12.8v but surely this would affect all cylinders. like i say have tried plugs and coils and these are fine i am…

I have posted this before i have a 95 yzf 600 that i bought and it would not idle you can pull the choke and it will idle i have replace the joints under the carbs because they were all dry rotted and cracked and that didnt help so i cleaned the carbs really good with cleaner and wire to clean the jets and used a air compresser and that didnt work i got the book and i saw that the pilot screws were out 2 1/2 turns so i put them at the correct 2 turns out and that didnt help i adjusted the throttle stop screw and got it to idle at 2 1/2 rpm it will do that for about 10 seconds and then die and also when i barly turn the throttle it bogs down and when i turn a little more …

Hi, Bought a 1997 P.reg thundercat a fortnight ago for a good price, replaced the front pipes and front tyre and put it in for a MOT Sadly it failed on stiff rear suspension, needs to have 4 inches of movement?? Also a leaky front caliper which i think just needs a seal kit The thing that is boiling my blood is the stiff suspension, is this a common thundercat fault or do they just seize up I think the bike has stood for a yr or 2, apart from these problems I'm very happy with the CAT Some advice would be most helpful Cheers Help me please, with a cherry on top

Any wiring experts here? Is it possible to wire the CDI and coil directly to the engine and do away with everything else? How would I do it? Thanks Mark
