heavy clutch springs for gpz 750

was wondering if anyone made a heavy clutch spring for a gpz 750? also while i am at it (replacing clutch this week, manual arrived so now ill do all the work!). i have seen "locking" cluthes for the 1100 is there one avalible for my 750? sorry for all the noob questions this is my 8th bike but my first bike as an "adult" when i was in high school i just rode em till they broke (the stories i could tell, i broke a drive shaft on a 77 gl 1000!)im in love with these air cooled in line fours!any help would be greatly appreciated.

The aftermarket springs for the 1000's will work on the gPz750, unless you are a professional weight lifter you might not want to go much over stock though.

The GPz750 FAQ covers the subject, take a look in the Links section on the bottom right side of this page.

Steell is correct. IMy bike mechanic buddy gave me a set of stronger clutch springs from his Z1 dragbike and the springs fit into my Kz650 without any re-working required. I put in a new Barnett Clutch at the same time and haven't had even a hint of trouble out of my clutch in 3000 miles of hard thrashing.

If memory serves, back in the 900 days, smaller valve springs (being firmer than stock clutch springs) were sometimes used to replace clutch springs for a tighter clutch grip, and without much additional lever effort.

Uncertain whether this could apply in your particular application, but might be worth an inquiry.

Not sure about the 750 but on a 900/1000, the available aftermarket springs are considered "heavy duty" and are stiffer than the originals. I try to use the oldest and most tired springs I can that will still move the plates back. The older springs have an easier clutch pull. I have a set of "heavy duty" springs in one of my test bikes and hate them.

wg i value your opinion but i am going for pro street i need the heavy springs . i am a fire fighter and a mover on my off days so the pull is not a prob. i may be wrong but heavier springs make a more solid clutch.?

how weird...im a firefighter too and am also building an 810 kit 750.... small world. now just split the cases and put in a 550 tranny like me. six gears.

EBC do some springs that are about 10% heavier than stock. Kibblewhite do some "red" racing springs that are a LOT heavier. MTC do a lockup for the turbo that would probably fit your GPz, but I expect you'll be ok with just springs.

Bwhahahaha A pro street for every fire fighter? Well I am a firefighter too... I am quartermaster for the MVFD (Mico Volunteer Fire Dept). We are rural and driving our trucks will make a man out of you! The one I drive, ol' 191 is a 500 gal (unbaffled tank!) tanker with a sign in the cab saying "TOP SPEED 45 MPH"... no power steering in that ol' truck (it is about 20-25 years old).

Anyway, goals for a bike are different... I ride sedately on my KZ1000E1... If I want to go fast, I ride my Bandit 1200S with a hydraulic (light pull) clutch. You are correct... heavier springs keep the clutch from slipping and are desireable in a bike where a higher level of performance and a rider with a go-fast attitude is on board. If I were going to build a go-fast bike, I would consider one of the hydraulic clutch kits and use some real heavy springs.

thats too cool man, not trying to change the origanal subj. please tell me more about the 550 conversion. at least 2 times a day on my local deathtrap (loop 820, i live in dfw) i look for 6th. the averave speed on this road is around 85, no prob my bike likes 90 at 6,000rpm's but i would really like 5k at 90mph.

wired G - that sounds like our tanker exactly to the T. cept ours has a purty looking eagle on the side. im on a rural community department too. man this keeps getting weirder and weirder. im interested in these racing kibblewhite red springs but something tells me theyd probably fatigue me quickly from stop light to stop light on the streets. i hear people talk about barnett springs and APE. what about these. whats a really good option for some stiff springs without going racing? theres gotta be some other fellas or gals who have an opinion on this?
