personally, if the bike is stock, replace the fork springs first. that is the weakest link with this bike in my eyes. then 351, good tires, and use the rest for gas money on a bad *** trip.

 

Ill buy the beer if you wouldnt mind getting together and let me pick your brain about a few things in regards to this bike. Maybe a little wrenching too......I've never really got in to a carb.......much less replacing a piston and a cylinder.

I'm not a XC'r........I just like the bike to jump when I twist. I would classify my riding as more trail riding .....rough gravel roads........I'd like to start riding more at some of the OHV parks around.

Let me know.......I'm just an old fart that likes motorcycles......

 

Listen to those guys with the 331 kit, they know of what they speak of.

 

Can you really get a big bore kit for under $1000 installed?? I know I have seen the kits from the $450 to $750 range but this doesn't seem like something a normal DIY'er could tackle

 

I'm not a mechanic, but, I can read, follow directions, have common sense, own two torque wrenches and know how to use them, have decent tools, good dexterity, and a willingness to learn. I had no problem doing it myself. Furthermore, I'm sure it was done correctly, and now I know more about the bike I'm trusting to not leave me stranded out in the desert.

 

Of course it is. Like Blackheart said - If you have basic tools and can read/follow a DIY, it's easy. Do a search and look a the procedure, it's easy. You can do the 351 kit for under $600 I think.

 

I'm trying to scrape up a kilobuck to do the BB kit too. I did my fork springs -- went to 0.48kg (0.43 is stock) and the difference is HUGE. I need a rear spring too but for now I have the rear one setup pretty well.

Now I'm kicking around between the BB351 and the KK330 kits. That plus the pumper carb and some sort of exhaust that isn't loud and doesn't require repacking.

you might want to check out the Cycle Pro 331 kit as well. Same as the KK kit but only $500 with the cylinder exchange. I'm installing mine this weekend.

 

I had never tackled working on a 4 stroke ever. But after reading up on all the threads to do the rejetting on the cvk, I read up on the big bore threads. You know what they weren't that difficult to comprehend. The guys who did those diy threads made it easy to follow. All I ever worked was 2 strokes. If I can do it anyone can, read up an get what you need ahead of time. It's not rocket science....

 

Always work with your suspension first. Save the rest and get comfy with the newly setup ride. Then go from there. The BB kits do seem like a good bet later on.
