92 GSXR 1127 engine into 750F Katana, [sick]

[Mista M]

Ok. Bike looks like a sleeper. May even I'll finish my 750 and us Michigan riders can meet up.

Bill, that swingarm mod would have me concern. I'd be welding on some big a$$ reinforcement plates over those weld joints. If one of those welds breaks you hit the ground.

[Buffalo Bill]

True, but seems I'm the 1st to do any reinforcing over that mod to a Kat swingarm. I was told by the guy who does many of these, that it don't need more bracing.
I have plates welded across the undersides where the separation stress will be, and I have triangle bracing above.
The cuts and welds are only on 3 sides of the square tubing.
A lot of people are concerned anybody should ride a motorcycle.

Bike is on the road!

Ok, long wait but I got the bike running and on the road, did 50 miles today.
Idle is still high at 2300 RPM, and that may be a cam and valve issue I don't wanna deal with during track season. This will work very well for a trackday bike.
I think I got a medium cool bike…

[Charlie G]

Medium cool? Hot, I'd say!

[Buffalo Bill]

Thanks Charlie!

[Carter Turk]

So when's the next trackday and where?

I didn't read all the posts, is there some reason it's idling so high?

[Buffalo Bill]

Next trackday, can't make up my mind, but this month. Wanna be sure of the bike, but no problems so far.
Also like to ride trackday at Road America last week before the July 4th weekend.
Why it's idling high? Wish I knew, I'm just an amateur engine tech.

Just got through reading your thread. Cool project Bill.

What are the dates on the track day. What organization? That is a sweet track

Very Sweet Organization: STT, Sportbike Track Time

My home track is Gingerman Raceway. A better track is Grattan Raceway.
If you're in Minnesota, maybe you wanna sign up for Road America >June 29 & 30!!!!!
Me, Road America = Legendary!!!!

Project not finished, damn!

Ok, so I got a wild hair up my ass to spend more money on my 26 year old Katana.
So I'm looking at replacing the steel subframe with an aluminum subframe from a 93 GSXR.


Plus a SRAD type tail from Air Tech, all fiberglass.


And I just purchased this 4>2>1 header and can off ebay


I dunno, I'm just a gas punk

[GS1150Pilot]

That's awesome. Go, gas punks!

[Buffalo Bill]

Thanks!

No interventions for you from this site. Only a bunch of enablers.
What brand pipe is that?
