Well, I just had lumbar decompression surgery and had disc fragments removed from my nerve canal. After two weeks now I ditched the walked and now starting physical therapy. I am looking at things to get for my TW200. I don't know if anybody ever thought to use a wiseco piston from a yamaha YFM200 or YTM200 (I've owned a ytm200 and it looks exactly the same), it ups the compression to 10.25:1 which is better than the stock ratio of 9.5:1. I've already ordered my needle shims and about 4-5 main jets in increments 115 and up (my stock is 114 california bike). In conjunction with the hi compression piston and fmf exhaust I was also thinking about doing the webcam's camshaft re-grind. I also have a ttr225 stainless header too I am going to shine up and put on. I'm not looking to make this little guy a power house, it just needs a little umfph for the hilly terrain I ride, and maintaining speed during climbs on road. I switched out the back sprocket to a 47t last summer and that really helped with getting it up to speed, now it just needs the power to keep it there (I am a little on the heavy side). I may also do the dual rear sprocket mod to have the versatility for when I take it strictly off road. I know I could get an xt350 and be done with it, but I love the mini bike feel and the big tires, makes me feel like a kid again. To date I think my bike has 3500 miles on it and she's an 88. I have a complete running 87 tw200 engine, can I just send that cam in to get re-ground as it looks virtually identical, other than they changed the wire harness/cdi/stator/pickup/etc. I am going to get a blaster shock too for the rear, I will have to make the kickstand longer too. Any thoughts? Thanks in advance.
