Yamaha R1 1999 clutch slipping problems

Firstly, you need to download the free PDF Yamaha R1 ‘99’ workshop manual from the internet. Also i have noticed that on various blogs there seems to be confusion as to what the correct engine oil to be used is and as you will see, any good 20W50 multigrade motoroil is what Yamaha have specified. I’ve had a few Yamaha R1 '99' bikes and i am a professional engine builder specializing in BMW V8 engine reconditioning. I have also built a few of these engines, one of the most wicked carburreted motors around.

The problem I have on my present ‘99’ engine, is when I top up with oil, adding lets say 100ml or so or when doing a completely new oil and filter change, the clutch assy slips for at least 150-200 km's and then subsides, as they all seem to do.

I have now come to the conclusion that the ‘old engine oil’ that gets imbedded into the friction plates is slowly replaced with the new blend of oil i.e. 'The 100ml of top-up oil or by the completely new oil added when doing the oil and filter replacement. This alters the state of the oil viscosity and forms a kind of barrier.

I usually change the oil every 3 to 4000 Km’s, so I am very familiar with the symptoms on this particular bikes engine. The clutch plates only begin slipping from about 9000 RPM, or when I hammer the clutch to get the front wheel airborne, especially when it's very cold out in Johannesburg.

There is no substitute for a stiffer pressure plate that I know of. I was told that a Yamaha FJ 1200 pressure plate would do the trick so I ordered one. They both looked identical when inspected before fitting and it made no difference at all to the slippage. My first '99' R1 never had this problem and I made x2 new Yamaha OEM clutch changes on that bike, also just for interest sake, I usually clocked up about 10,000 Km's on a new clutch before changing again. The only assumption I can make is that the clutch baskets coil springs weaken? Presently I am building an engine which has only 8000 Km's on the clock, so we will see how that clutch assy performs.

Lastly, I heard that there is a clutch that is slightly thicker and apparantly what the guys do is fit two of these slightly thicker clutch and/or friction plates in the middle of the stack. The PDF workshop manual stipulates the min and max thickness of the entire clutch plate stack. To me this sounds like an option that should work. Surely someone has the answer to the problem, or is Yamaha selling us superseded kits that have actually been designed and tested for later model R1 engines?

Road Accident Fund | Road Accident Injury Claim

A motorist and/or his passengers including any pedestrians who have been involved in a ‘motor vehicle accident’ (MVA), whereby the driver or the occupants of the vehicle and any third parties who have sustained injuries due to negligence or for any other valid reason, have the right to claim for compensation with the Road Accident Fund (RAF) of South Africa within 3 years of the accident by lodging a 'Road Accident Injury Claim'.

Most people don’t know this and do not know how to go about claiming for their injuries. You as a motorist have every right to claim for injuries when involved in a motor vehicle accident where severe whiplash, which is a common injury to the neck, commonly sustained by motorists who are lucky enough to walk away from the accident scene with neck pain and concussion.

This type of injury may not seem traumatic at the time due to the shock and impact of the incident on a person and the victim often shrugs off the pain and stiffness experienced by taking sedatives and/or muscle relaxants such as Myprodol or Cataflam for a few days thereafter. The question is, are they doing themselves more damage than good by not consulting with a doctor and having the area of pain checked out ?

Most 'injuries' often go untreated for a number of reasons and above all, the lack of medical aid cover is problematic in many instances, therefore ‘knowledge is key’ in this arena. Anyone who is involved in a MVA has the right to claim for severe whiplash or any other severe injuries sustained as a result and this includes passengers and third parties. Provisions are also made by the (RAF) for and whereby a family 'breadwinner' has passed away as a result of a MVA, enabling the next of kin to lodge such a claim.

The South African Government makes provision for legitimate road accident claims that are filed through a specialist law firm or attorney. For every litre of petrol sold at petrol stations, a certain percentage is allocated to the RAF for such claims. It is the right of every motorist to have access to the RAF organizations funding when a severe injury is sustained in order for them to get the professional medical treatment that they deserve in order to verify the extent and nature of any such injury.

The RAF is bound to legal and medical practices and therefore any valid claim a motorist, passenger or pedestrian may have would need to be filed appropriately. Claims usually take between twelve to eighteen months to be finalized and are subject to RAF practices and litigation.

Should you be a RAF candidate who has been injured in a motor vehicle accident, that meets the above criteria and you have reported the accident to the South African Police and you have a case number there should be NO reason why you cannot claim for the injuries that you have sustained and get 'paid out' for pain and suffering and/or loss of mobility in any way whatsoever.

A Claim expires after 3 years if not lodged and 2 years if it was a hit and run case. If the claimant is a minor, under the age of 18, the claim will expire 3 years after his/her 18th birthday.

If another attorney was appointed and has lodged a claim we still have a good chance to do a claim for you.

Don’t waste any more time ! CLICK HERE road-accident-fund-injury-claim-form and complete the claim form and you will be contacted back within 48 hours by the most prominent Attorney's in RAF law who will immediately start your claim process and fight for your compensation.

N.B. No upfront payment is required. There are NO hidden costs whatsoever. Your claim will be filed immediately.
