Before you replace the sprockets, check them for wear. They usually dont go bad. That might save you some money. Make sure your tensioner is working correctly and replace any parts thats needed. I would have the cylinder checked for clearence with the new piston (or old if its still good) and make sure its within specs. If so hone the cylinder, toss in a set of rings, valve seats (comes with top end gasket kit) and a new timing chain and guides. Also with a knock/tick like that check the rod for up and down play. It's normal to have some side to side play, but NO up and down.

Well the only reason I said sprockets is in the manual it says to replace those with the chain but if you say itd be ok w/o them i wont. Im gonna take my cylinder to a local dealer and have them hone or poss. bore. Theres 3 things im worried about: 1) Doing the valve seals 2) getting the rings onto the piton and in the correct order. 3) Getting new rings and piston into the cylinder.

On Bikebandits fiche what # are the valve seals?http://www.bikebandit.com/houseofmot...225drn/o/m8794

The rings are easy, they come with instructions. Also take the piston to the dealer with the cylinder to have it checked for tolerances when they bore or hone it. You cant just hone a cylinder and reuse (well you can) but its not right. You need to hone to fit the piston within specs. If its too loose of specs you will have to goto the next bore and buy a new piston. With an engine that sounds like that, i would bore it 1 size over just because. Get a manual before you do anything. It will be a life saver.

valve seals are simple if you have a valve spring compressor for overhead valves

valve spring compressor i guess ill have to look for one lol

lol yes they are i got a whole sset for christmas one year i think almost every pice is bent or broken. Anyway i was looking on ebay for an actual spring compressor would this work?http://cgi.ebay.com/ebaymotors/UNIVE...item4399f4e3de

Would this help me get the rings into cylinder the stock size is 70 so i think it would?

^ I think the valve spring compressors are going to be too big for the job you are doing. For the piston rings, if you really cant get them to go into the cylinder for final instalation there is an old school trick : a large hose clamp! Find a hose clamp big enough to fit around the piston, then tighten it down to compress the rings. You dont need it too severly tight, because the goal here is for the clamp to slide down when you push the cylinder down, thus letting the rings and piston into the bore. Good luck, and hope this trick works out for you.

I just use my fingers to push the rings down and slide the cylinder over. Its not hard at all. Just relax and take your time. If you doubt yourself about anything, post it on here and we can walk you through it.

**Kerick** · 12-04-2009, 10:43 PM

OK update I finnaly got some free time today and I wennt out and started to tear it down by manual. Drained oil, disconectedd - on batt., took of fenders seat tank, Then i went to take off the pipe and got the right allen wrench tried turning wouldnt budge so i got a small pipe and put it on the end and turned and now its stripped this sucks i hate seized bolts. Thats as far as i got

what he said.. try to take a mental note where all the dowels go. and o rings,, take pictures if you have to..

cut the head off both them bolts for the pipe..mutch easyer to fix out of the bike.. just plan on puttin new ones in.

I put a couple pieces of wood under the piston so it will hold it in place and not tip back and forth or want to turn the crank. Use wood thats nice and square and clean, or if you have square plastic, anything that can't scratch the piston or damage the base gasket. Might not need it since its only 1 cylinder but it will help if you are having problems with the piston moving around on you.
