Suzuki 2 Strokes

Redoing a low miles '74 gt750. No reason to suspect seals but since I have to pull the barrels to have several exhaust bolts drilled and tapped by the machine shop might as well do the crank seals now. Don't want to open it up again for the rest of my lifetime .

Recommendations? Prefer to keep it southeast US due to time/shipping costs. Local machine shop has a place they recommend that does 'all their dirt bike 2 stroke cranks', but I don't expect they'd know what to do with a multicylinder crank.

Falicon can do it but they are rather expensive. The rest of us box our cranks up and ship them to Bill Bune in MN. Wrap it well and insert it into a lockable plastic tool box and it should be safe.

Bill Bune just did my GT750 crank, quick turn around time. Cost was $202 with my seals + shipping.

I'm still rebuilding the GT750 cranks We are in Muskegon Mi.

Red rebuilt my GT750 crank last winter and did a quality job. The engine's since got 948 miles on it and runs like a champ.

current issue is still the damned barrels. Fabricating the barrel puller from heck right now to get this thing off of here. Simple half inch plate bolt down puller didn't work, just snapped head bolts and pulled the threads out of one.

I expect the new one to either pull the barrels or break them in two

I tried a puller on 2 different motors and wasn't getting too far, so I use a method recommended by SuzukiDave. I took a large tap and cut a thread into all 11 sleeve nut tunnels and then used matching bolts to press down on the studs.

Every couple of turns teh bolt has to come out and be tapped deeper, so it's not fast. Pressure has to be evenly distributed and it still takes heat, patience and drums of your favorite rust remover/penetrating oil.

Yes I've seen the posts on that method and it's option '2'. First will be my rebuilt puller that attaches to the exhaust and intakes.

Too damned hot here to get much done. I managed to beat the old plate straight yesterday and cut a second reinforcement plate. If it ever cools down I'll weld them up and then drill the new holes, after that it's just cutting the steel for the port attachments and more welding.
