Intro and a question.

[TZ350]

Ive got a fairly decent idea of how I want the motor to sit. Ill have a browse through that colossal ESE thread and see what I can dig up. Cheers all.

Using the thread tools to view the pictures and sorting them 70 (70 is the max) to a page and trawling through the pictures is a good way to find the interesting stuff also on every decade page starting at page 80 is a collection of good tec links and quotes from the last ten pages. Good Luck

OK ...so not very good photos, and I am not saying this is the best way to do it either, its just what we did ...

I make it 145mm between sprocket and pivot center to center on our bikes. We had to move the engine forward to get enough weight on the front wheel and to be able to use 13-14T sprockets without draging the chain heavily over the swingarm.

With no one aboard the chain tension is quite slack, we all ways set the chain tension with someone on the bike so the swingarm is level. When we made the engine plates we made the sprocket and pivot level. if we were doing it again we would raise the sprocket 5-10mm and may be the engine a bit further forward still 10-20mm for more front end bias.

The bikes are far from "proven" but they have done a few laps without trouble.

PS my 4" was from edge of sprocket to front of SW, but its as approximate as heck.

Hey all. I guess I better introduce myself. Im Nick, Ive been riding a mere 6 months on my 77 cb550f. Absolutely loving it.

Ive recently picked up an old 3ln fzr250 frame for the purpose of bucket racing. I sourced a suzuki gt125 twin for the engine and im attempting to somehow mate the two to form a passable track abortion. Im not terribly clued up when it comes to bike setup, and Im wondering where a good spot for the engine would be. Im assuming I'd want to keep the weight fairly low? But how far forwards/back would I want it? Again, Im assuming centrally regarding the bikes overall weight? Feedback much appreciated.

Cheers, Nick.

all these newfangled sprotsbiker idiots mount their engines somewhere in the middle for 'even weight distribution' but since buckets excel on tight twisty stuff, Id suggest that for more front end grip in the tight corners, you should attempt to mount the engine forward of the forks.

was trying to find a pic of a y intake for the twin but couldn't (have seen it on the bench with a single carb. will take pics if I can find it again)

[Moooools]

I think this is the one you are after.
