  1. These guys produce some nice rearsets - https://accbilletengineering.co.za/product-category/gsxr-pre-sling-slabside/
  2. Sorry a bit more context. I read the valves and or seats have a thin hardened layer and that lapping them in can wear through the layer so shouldnt be done. Sounds like most do lap the valves in.
  3. I used a Yamaha YZFR1 YZF R1 1998 1999 2000 4XV Right Hand Switch
  4. Quick question. Is it ok to lap in slabbie valves with a light lapping paste? Read a bit that says no, dont do it and other posts where people do.
  5. Hi @DezzaNo it wasnt changed, measured length to ensure it was in spec. I assume if I end up looking at the big ends and splitting the case then that would be the perfect opportunity to put a new chain in.
  6. Dang, hope I don't have to as haven't done it before. If I dont get anything with valves and springs I will look at that adventure
  7. Or you could look at an APE ST750 manual cam chain tensioner. http://ape-store.com/shopsite/page5.html https://aperaceparts.com/tech/tensioners.html
  8. So still trying to figure this out. Torn it down and removed the head, going to check valve springs ok, Cam chain is fine and tensioner and guides. Having a look at the camshafts again the cam lobe profiles arent very even, one side is very steep. I am not familiar with how the cam lobe profiles should look. Any thoughts on below? Do they look ok? No ridges on the lobe faces
  9. Also does anyone use thread lock on the camshaft cap bolts?
  10. Hi, GSXR 1100 Has anyone replaced the camshaft cap bolts? Are OEM best or do most people just use high tensile steel cap screws? Any change to torque settings or just follow the manual?
  11. Cam chain was tight and not loose. Idler sprocket bearings fine. All cam caps still tight no bolts broken. 1 cam bearing showing some blue so possibly a bit tight wit cam cap and binding and overheating. No major galling on cam surfaces. Bit at a loss. Any concerns looking at the photos? Will look to spruce the cam chain tensioner. Have a few cam caps to helicoil as cylinder head cover threads stripped on a few.
  12. @bluedog59Thanks good advice. The carbs are flat sliders and chatter at idle, they have been balanced but will check again
  13. @Hanma-shinDo you mean the wheel in the cam chain idler? Number 3 in the parts diagram
  14. Compression Test Results: Manual Std Compression: 142 - 199 psi Min: 114 psi Max Variable: 28 psi Bike Results Initial psi / Final psi Cylinder 1: 140 / 178 Cylinder 2: 140 / 180 Cylinder 3: 140 / 170 Cylinder 4: 140 / 175 Keeping in mind it is an 1109 with high compression wiseco pistons. Also I haven't ever done a compression test on a slabbie but followed manual instructions Diagnoses: Initial of 140 psi I will assume is great on first crank? If so valves are sealing well . Built to max pressure quickly so rings good. Variation within
  15. Hi @Nik Bored and honed and 1109 piston kit fitted 6000 km ago bang on clearance. Very unlikely piston slap
  16. Thanks for all the suggestions, appreciated. The rattle is easier to hear with the 2 revs at 32 33 secs. Ill do the compression test rule out ring and values, drop the oil and check,, pop the cam cover again and check cam chain tension and cam bolts. I think this time ill actually pull the cams out checking the bolts and the bearing surfaces. Typical as I have a race in 4 weeks.
  17. Hi, 1987 GSXR 1100 - Engine has Wiseco pistons bored out to 1109. Done maybe 6000 kms since rebuild. Std Cam and springs. Head had a bit of work with ports cleaned up. Idles fine, performs fine. But a bit of a rattle with revs, sounds like top end, maybe cams? Popped rocket cover and checked and set valve clearances, all good. Any clue on the noise? Plan on doing a compression test later this week.
  18. Full fairing, no airbox (Pods). Yup saw Motorcycle NZ rules state it cant be open to atmosphere. Bugger better make sure I use oversize tubing as would not want to obstruct the vent and affect the float bowl fill rate. Will run them, into the same catch can for overflow pipes.
  19. For those that race do you do anything in terms of hosing for the float bowl vents? The carbs come with float drain hoses but the float vents are not supplied with hoses.
  20. Ive replaced these spherical cups before, was pretty straight forward so if your solution doesn't work out get new ones.
  21. Just a thought but I had bot my tacho and speedo jump around when riding and found it was the mountng rubbers gone and the dial rubber mounting surrond. Changed those and all fixed
  22. Perfect - Thanks for that I didnt realize it was replacable. I see it is part 6 in the digram sorry mate
  23. The part you listed is the thumb screw nut Not the pivot point
  24. 87 GSXR 1100. I have a headlamp loose and rattling because the plastic pivot is broken. Tried to see it in parts exploded diagram but it aint there. Essentially there is the finger screw adjuster and a philips head adjuster and then on the opposite diagonal a little plastic socket. My socket is semi busted so I am after hacks or fixes to secure the lamp plug to the socket. e.g. Drill a few holes and hold the lamp plastic rod in socket with some cable ties or rubber bands? Any hack suggestions?
  25. ok SO the mickey mouse ears were good and the general rubber gasket. However all the gaskets (number 7) for large hex bolts number 5 were not installed and the gasket number 10 for hex bolt 8 are steel washers and not a gasket. I have ordered a complete new set as well as the head bolt gaskets. So I am hoping the oil when the engine was under high revs was pissing out the head bolts leaking down the spark wells and then spraying around once out the drain holes in the front of the engine. Lesson learnt. Now to loosen off head bolts and retorque them back down. Damn get
