Default few random questions.

I put the actual questions in blue and extra info in black, I'm OCD like that... ha ha

A) what is your "Cruising RPM" range?
my Vance and Hines is so loud i feel weird riding above 4-5k for an extended period of time, but it also seems to run kinda boggish in that range too....

B) has anyone tried drilling holes in the heel guards and putting some stubby pegs in (like 1-2 inch pegs just for a higher foot rest)? I don't want to drop the extra dough on new rear sets just yet, but i'd like the foot pegs higher up for comfort reasons. Just a ghetto-mod idea ha ha

C) Like mentioned above, my bike seems kind of boggish if i ride at 4-5k for an extended period of time, it also pops flames on mid to high range shifts. I've dropped the jetting down to non-cali stock jets, do you think its running rich still? Its a 96' F3 california model, K&N and Vance and Hines SSR2 exaust and ignition advancer, jetting is 135|138|138|135,I'm also at high elevation....
So Would I be better off A) turning my pilot screws in some, B)putting my needle clip out one, or C) putting even smaller jets in?

Thanks!

I cruise anywhere between 3500 and 5000. I get a weird hollow rattly noise somewhere between 4 and 5 so I usually stay under that in town, but I sit closer to 5 when I'm out on the highway. My boyfriend has gotten on me for shifting too soon, so I'm actually interested in how other people answer that.

around town i cruise at around 5k rpms, However since going up some teeth on my rear sprocket on the free way it's around 6-7k rpms. Even in the twisties I'll keep my rpms closer to 6k, a know a lot of people will be at around 10k when railing but I find a smoother throttle response at lower rpms.

A) what is your "Cruising RPM" range?
Now that I'm used to a 4 cyl vs the singles and VTwins I used to ride, I've learned to keep it around 5500 RPM or so.


B) has anyone tried drilling holes in the heel guards and putting some stubby pegs in (like 1-2 inch pegs just for a higher foot rest)? I looked at that, but don't know how strong those heel guards would be for supporting a set of foot pegs. Especially after drilling into them. Many of the replacement rearsets out there don't look to be very adjustable for or F3's anymore (I saw some Diamond Rearsets from th UK on a bike in a magazine that looked nice and adjustable, but they're no longer in production).

One option is to make up some brackets that move the stock reasrsets back and up, I saw a thread on here somewhere about it, and it moved the pegs up and back about an inch.

It may also be possible to make up some brackets with a few different holes to relocate the rearsets in different positions, but I haven't had time to look into drawing any up yet.

I think on the Highway mine is in the 7k range, but I think it is due to the original owner going -1/-2 on gearing might be the stage 2 jet kit too. Not really sure

-1/-2 is a kinda pointless gearing change, its the same as not changing the sprockets from stock

found this site with some really good info- and... it had a pre-designed rear set riser plate template that appears to have 4 positions, i'm gonna take it to my buddy that does machining to see if he can make some up for me. then i'll just need to modify the shift lever and brake lever if they prove to be difficult to opperate with the new positioning.

the site can be found here >>>> http://racebiketuning.com/cbr600f2-e...ort-race-bike/
