Help please

[Phil Davies]

In the circles of racing two strokes what is used these days to seal those warped and mangled crankcases - especially for TZ750 engines.
Back in the mists of time we used Suzukiseal (designed for the RG500), cannot still be current - surely??

Any help appreciated.

The black Three Bond used by Suzuki, Kawasaki and Honda is good Phil . Years ago we tried not to put too much bond on TZ cases as it encouraged those crappy bearing pips to gouge there way around the bearing journals.

If you have a 750 TZ,you can send the cases to Les Cross, and he can do an o ring conversion. This eliminates the need for 3 bonds around the crankshaft area, and even works with mismatched cases. He has done 2 of our cases,and it has completely eliminated breathing pressure in the gearbox.Oh,and a blob of Loctite on the bearing locators,to stop them spinning,or if you have the facilities,put longer pins in the bearings.

Thanks to all that responded - as a result I have now found the stuff I was looking for.
Tony, thanks for the advice, I've only ever used non TZ bearings but in conjunction with advice from Loctite tech dept (big up for those guys).
Never had a problem (that I knew about) with gearbox pressure - but I don't follow 'the manual'.
Last time I used an axis jig on a set of my cases it frightened me that a 'component made for racing' could be that crap!!
