steves moped....does any1 no what part to shave? or grind

Re: tomos 31 tooth front sprocket help

You have to grind a little bit of the engine side but most of the material comes off the mag cover (alot) best is to get a 1/4 in carbide burr and air tool ,"die grinder " and use finesse. Keep grinding until chain clears....If you have A55 motor this sprocket is to big you have get a old A35 ignition rotor setup so the chain will clear...this mod is worth the trouble!! also get the 20 tooth rear and fly on the top

Re: tomos 31 tooth front sprocket help

y wont it work with an a55??...and also ive tryed a 20 tooth rear and a spaced it out with washers but there is an alliment problem

420 chain to take the alignment out. Not the best but will work.

Re: tomos 31 tooth front sprocket help

If you have a early A55 it might have the crank sensor on the inside of the mag ...the sprocket will work ....If you have a newer A55 the crank sensor is on the outside and the 31 tooth sprocket will hit it. If you take your time and grind the rear wheel you can run that 20 tooth with proper chain alignment

Re: tomos 31 tooth front sprocket help

pretty sure i have an older a55 i got it wen it first came out...ill check the mag tmr...thx 4 all the help...1 more question..if i put the 20 tooth on and the 420 chain wnt the front one be dissalined then?
