Stephtell Posted February 13, 2016 Posted February 13, 2016 ...the clutch shat itself... Basicly it was making more power everywhere and boostcontrol was MUCH better so all seemed well whilst we were slowly upping the boost and adjusting the fuelling to suit...BUT (there's alway's one, isn't there?) the clutch decided to let go... And not just any clutch: A Hayes convertible clutch...it sheared the cover of the basket, ripping the basket and smashing the plates whilst at it so won't be a cheap fix then... Properly gutted BUT (See? There really always is one!) very pleased I was right with regards to the exhaustmanifold and linkpipe! Quote
mick-ne Posted February 13, 2016 Posted February 13, 2016 I bet the clutch wasn't the only thing that shat itself,lol. Nowt worse than you ride destroying itself, hope the repair is as painless as possible mate Quote
Stephtell Posted February 13, 2016 Author Posted February 13, 2016 You're right, my wallet is next to shit itself I'm afraid... Main thing is that it's running sweet with plenty 'o power and more to come! Quote
IanC Posted February 13, 2016 Posted February 13, 2016 Better the weak spots show up there than while out riding. Quote
Stephtell Posted February 13, 2016 Author Posted February 13, 2016 Fair enough but you wouldn't exactly expect a clutch like this to let go... Quote
IanC Posted February 13, 2016 Posted February 13, 2016 I'd probably contact Hayes and see if they have an ideas why it would have failed. While I have no doubt you are making some serious power figures I would doubt they haven't dealt with higher. Quote
Stephtell Posted February 14, 2016 Author Posted February 14, 2016 Agreed. It seems they have changed the basket design since mine was bought so might hold a clue... Quote

Leblowski Posted February 15, 2016 Posted February 15, 2016 Not straight cut Crank to clutch basket wich causes powerloss and might destroy your Crank because of sideforces. My Crank was worn after three years Quote
Stephtell Posted February 15, 2016 Author Posted February 15, 2016 (edited) Well power isn't the issue here, it's making plenty!...is it possible to convert to straight cut gears that you know? Might be worth it seeing as I have to order a new basket anyway Edited February 15, 2016 by Stephtell Quote
Gixer1460 Posted February 15, 2016 Posted February 15, 2016 Not with that crank - would need a GSXR type and the matching clutch primary gear / hub 1 Quote
Duckndive Posted February 15, 2016 Posted February 15, 2016 7 hours ago, Stephtell said: Yes, why? Big Power & Helical Gears not play together very well as it tends to push / send the clutch basket out the case's to change to straight cuts you need either a GSXR Crank and Clutch Basket or Blandit Crank & Basket..... 1 Quote
Stephtell Posted February 15, 2016 Author Posted February 15, 2016 Oh dear....engine out job then...hmmm...will have a little think of how to proceed then....was thinking to not take the engine apart for a while and then upgrade to larger capacity as well but I don't fancy shelling out for a new engine just yet... What is big power by the way? The aim and probabillity here is 300 ATW...too much? Quote

Well the GSXR1100F was more of a lower power budget tourer style bike hence the helical gears and only 34mm carbs ...as opposed to the GSXR 1100 K , L and on which were sports bikes 36MM 38MM and later 40MM carbs all having straight cuts ......the B12 got straight cuts by virtue of being a K ,L motor with more cc but less punch in the cam dept.. If it helps I have a B12 crank that needs a regrind on one BE journal and I,m sure I have the matching clutch basket.... Big Power well 300 is a big hope on helical's IMHO ..... I put Straight cuts in my poxey 200 BHP air cooled motor Quote
Leblowski Posted February 15, 2016 Posted February 15, 2016 Pretty sure an F engine is capable off withstanding massive power. My slabby did 240 nm off torgue nothing exploded for three years and this was with standard basket. Thing is it wears faster i didnt split the cases from that engine but i bet the alloy half moon shims between the crank and cases are fubarred. btw i was warned for this but i took it for granted.

Stephtell Posted February 15, 2016 Author Posted February 15, 2016 Thing is, I don't feel like shelling out for a new Hayes clutch only to have it explode on me again...so maybe it's better to not take that risk and upgrade to straight cut gears.... 1 Quote
Leblowski Posted February 15, 2016 Posted February 15, 2016 It was the reason that i went for a gsxr engine on my bakker and the sticky clutch problems wich can occur with gsxf engines Quote
Stephtell Posted February 15, 2016 Author Posted February 15, 2016 Crap...the engine is sweet as a nut so it would be a real shame to take it apart...unless I up the capacity whilst I'm at it...! Quote

You don't have to pull the top end off to swap the crank.....splitting the cases to do the bottom end is a days work........ Can I ask why you opted for the Hays Convertible Clutch ? Quote
Stephtell Posted February 16, 2016 Author Posted February 16, 2016 Ah, right...totally forgot that the cases split horizontally! The Hayes was already there and it won't slip and can be setup different way's which is kinda cool...thought it would be bombproof but, as it turns out, it's not... Quote
Stephtell Posted February 16, 2016 Author Posted February 16, 2016 BTW. I do have an OEM clutchbasket I think...how's about I run that on low boost for now? Quick and easy fix for only the cost of new plates I should think... Quote
Leblowski Posted February 16, 2016 Posted February 16, 2016 Well I had a stock clutch as mentioned, you will need a lock up though dunno if the Hayes lock up fits a standard clutch? Quote
