berty Posted July 8, 2015 Share Posted July 8, 2015 (edited) anyone else ever suffered with slow cranking probs? (apart from after Friday night at the dog and dragon)Have 1170 wiseco, good battery, good earth /leads and good starter plus tried other starters just in case.stock cams at stock settings.ignition timing bang on - both static full advance and strobe @ 3500 checks marry up well.any advice /experience ??

KATANAMANGLER Posted July 8, 2015 Share Posted July 8, 2015 (edited) Yes it's quite common on the ET with 1170 kits. The answer , I believe, is to fit and EFE starter motor and intermediate starter gear . This solves the the problem. @Deeds did this just a couple of weeks ago because he had the same problem on his 1170 ET. Edited July 8, 2015 by KATANAMANGLER 1 Quote Link to comment
berty Posted July 8, 2015 Author Share Posted July 8, 2015 had read somewhere about install momentary switch on ignition to allow cranking speed build up, or manual retarder.will look into the efe adjustments. thanks Quote Link to comment
CockneyRick Posted July 9, 2015 Share Posted July 9, 2015 Will this work on a GS1000? Quote Link to comment
Screwriverracing Posted July 10, 2015 Share Posted July 10, 2015 Or two batteries and 24 volts to the starter.Cheers SRR 1 Quote Link to comment
berty Posted July 12, 2015 Author Share Posted July 12, 2015 Or two batteries and 24 volts to the starter.Cheers SRRwas my initial thought but a lot of extra weight , and the thought of dieting to compensate was more than I could handle !! Quote Link to comment
coombehouse Posted December 1, 2015 Share Posted December 1, 2015 (edited) You could try changing the starter to the Mitsuba sm229 field coil type as fitted to older GS motors. They are a straight swap for the ND permanent magnet type & seem to crank faster particularly if you use bigger battery leads & a Motobatt battery. You can rewire them to 6 volt too they crank even faster then but I don't understand how to do that. A guy called Paul Cashio in the US does this.

FBJ Posted December 3, 2015 Share Posted December 3, 2015 I did the efe starter swap on my 1170 kat. Worked a treat Quote Link to comment
Gammaboy Posted December 3, 2015 Share Posted December 3, 2015 The other trick is to pull the advance mechanism apart, and grind the inner stops off the bob weights completely - retards the ignition at starter speeds over stock, max advance stays the same. Worked a treat for my high comp 1170 1 Quote Link to comment
berty Posted December 4, 2015 Author Share Posted December 4, 2015 Food for thought indeed !! Quote Link to comment
Gammaboy Posted December 4, 2015 Share Posted December 4, 2015 Here's a shot highlighting what you grind - if you just knock it back to flush with the rest of the bob weight, it works pretty well. Italso slows the rate of advange a tiny bit, which helps with the pinging at ~3000rpm that these things can suffer from. Quote Link to comment
berty Posted December 4, 2015 Author Share Posted December 4, 2015 Are you grinding on the end face or face that sits on the cam ? Quote Link to comment
Gammaboy Posted December 6, 2015 Share Posted December 6, 2015 (edited) Face that sits on the cam - just removing the step.Highlighted in red below: Edited December 6, 2015 by Gammaboy Quote Link to comment

Just to update - the Efe intermediate starter gear I have found to be 2.4mm thicker front to back . Which fouls the geny cover sitting Flat by about .5mm . Glad I noticed geny cover rocking - prior to the introduction of any bolts . Worth checking if anyone is thinking of this mod . Edited December 21, 2015 by berty Spelling Quote Link to comment
Duckndive Posted December 21, 2015 Share Posted December 21, 2015 ET uses a shim on intermediate gear ...EFE don't..... 1 Quote Link to comment
berty Posted December 22, 2015 Author Share Posted December 22, 2015 Then I stand very much corrected . I assumed the Efe had the 2 Shims / washers as with the et . Does it not cause wear without those shims ? Quote Link to comment
