I decided the old girl deserved a treat

I got a new 4stroke air filter from Sick Bike Parts
(shipped amazingly fast, thanks guys !!!)


and a flex exhaust from Quenton Guenther (the pres of EZM,,,also shipped very quickly)


the filter looks great, much less 'lawnmowerish', and the engine can be heard sucking, through it's much improved air flow !!!

the exhaust looks really nice too, and the sound on backing off the throttle reminds me of headers on a V8

but the big power increase was surprising, I can go up some hills that used to slow me down with no loss of speed at all, and only a couple of mph slower on the longer, steeper ones

GREAT news Bill!
Sounds like it's running much more efficiently now.

Do you really have 11k miles on the bike?
...excellent!

Bill, how does the flex exhaust attach to the motor?

 

[Tad Bit Tipsy]

I've been enjoying the new air filter for a while now Bill, and after a small adjustment to the carb, it has been quite a difference! I also gutted my standard exhaust.

 

[azbill]

the exhaust is mounted to a stub from an old 2smoke exhaust, a seatpost clamp holds her tight

I also had my exhaust gutted (all innards were gone up to the endcap)

I ran just the new filter for about 50 miles to see the difference before installing the pipe and opened my air/fuel mixture about 1/4 turn,,,after doing the exhaust, I opened her up a little over 1 full turn

I am amazed at the difference in this little engine, it is like a new bike to me all over again !!!

Bill,yes it is amazing what these two little mods do.I have a velocity stack from AGK I put on a few years ago and a homemade flex pipe was added late last year.Your bike looks great.
