:p :p :p :thumbsup: finaly ive got a minibike, its the honda xl75 that i was talking about earlier. got her for $100 with a box of parts and a spare front rim. started first kick and idles really well but wont rev up, i suspect its the coil or the sparkplug but could be wrong. the exhaust is rusted out so could i just put a straight through exhaust or would that effect the tuning? ive allready thought of a name for her.....THE HOG

we took the carby off and cleaned all the jets and whatnot and put some new fuel line on it, and it still runs but wont rev

What do you mean it wont rev up? Does it bog? Backfire? May sound stupid but is the throttle cable broke?

Also, don't put a straight pipe on it. These engines are a bit more touchy than a regular 6.5 clone or briggs flathead etc. If you did, be prepared to re-jet because you'd smoke the valves and it wouldn't have nearly as much power as it would with a stock exhaust. Just look on ebay and get the right stock replacement.

Check your throttle cable first off if it wont rev, and it definatly isnt the coil or plug, if either of those were bad it wouldnt run at all.

Adjusting the spokes is a real *****, seriously unless you have an excessive amount of patience get it done by someone else. You have to adjust each individual spoke to keep the wheel straight you cant just crank them all down, so basically you sit there spinning the wheel and making tiny adjustments to each spoke until you pulled the rim so that its spins straight. I get mine done (for my bicycle) at the local bike shop, i think it was like $50 for both wheels when i let them get excessively trashed (rear wheel was twisted so bad the knobs were rubbing on the frame). Also where did you find the price for that tool i own one and i think i paid like $10 for it (and used it once).

Really like the bike by the way. I wish i could have gotten a deal like that instead of trying to build my own.

yeah, its been in the mud and water a fair bit so all the tightining thingys are all rusted in place, im just guna take to a motorbike place and get them to do it for me. also when i lift the back end off the ground and hold the clutch in while in gear the wheel spins slowly, would i need new clutchplates or does it just need to be adjusted

You can adjust it a bit, but that's pretty normal. As long as it doesn't rev really high when its not going that fast when getting into the upper gears you're clutch plates are good. I know my 200 needs new plates in 5th and 6th it slips like hell.

you can just tighten up the spokes with an adjustable wrench. let all the air out of the tire first though or youl twist and pop the tube if its got one. just do a little at at a time and criss cross around the rim. just tighten it enough so there not wiggly anymore dont overtighten them

im actually surprised how fast it is, its a 30 year old bike with a bent wheel and it still hauls me along. a 125 will be really good for trials and hilclimbs
