The Swarbricks come as a kit and you have to weld them up.Įric Kalamaja does an excellent job porting the T500 cylinders and can angle mill the intakes for better performance as well. Their racing pipes are copies of the Swarbrick racing pipes available here: The street pipes allow you to keep the centerstand and kickstand where the racing pipes require you to remove the center and kick stands and cut off the mounting brackets so the pipes tuck in correctly. They have the T500 street pipes listed on their website at $400:Īnd they also offer racing pipes at $600 or so. Personally, I'd check with Jemco to see if they can repair the chambers you have already. Muzza covers the oil modification in detail here:Īnd also talks about porting and performance modifications here: He's on ebay and here's a link to one on auction now: There's a guy in Tennessee that is reproducing the mission plates and they are accurate (I loaned him an original to copy). Of course it could have been modified sometime in it's life with the rubber 'mission plate' Suzuki produced for this purpose and you'd probably have to crack it open to verify this unless someone engraved 1400cc in the cases or the cheesy '1400cc' sticker Suzuki provided with the mission plate is still stuck on the cases. The cases will have either 1200cc or 1400cc cast into it by the oil fill hole. Regarding the oil mod - check your crankcases to see if they are later 1400CC cases - Suzuki modified the cases in '74 to correct the starvation issue for 4th and 5th gear. You can put together the equipment you need for a pressure test for about $20 and I describe what you need and how to do the test here: Test the compression - the bike will run on 100PSI per cylinder with a +/- difference of 5PSI between the cylinders but you really should see 120PSI to 140PSI with everything working as it should.Ī good test of the crank seals is to do a pressure test and see if each side will hold 6PSI for 6 minutes. Have you riden the bike yet? As Ken posted, figure out what the bike needs first. Can you post any pictures of it? 34mm Mikunis (32mm are stock)and Jemcos? I'd be willing to bet it's been ported already.
