who knows the best way to run a engine in?

Question

for best power for top speed

i have got a yzfr1 year 98.s reg

Answer 1

modern engines dont need running in you would do more damage

Answer 2

Modern engines are built to such close tolerances that they are the equivalent of 70% run in when new, so most people drive flat out from day one. I adopt the following, even with expensive German cars and it pays dividends. Keep the revs down, but don't keep it in too high a gear just to achieve this. Pulling gently runs it in, revving ruins it. In other words ride as if being followed by a policeman, but don't use motorways. After about 500 miles gradually build up to normal speed and use. Never push a cold engine. This is the period when 35% of all wear takes place. Use the best petrol company oils. Oils actually 'wear' and cheaper ones wear quicker. Redlining etc halves the life of an engine. High speed cruising well within the rev limit is OK.

Answer 3

It all depends what bike you've got. Let me know and I'll say more mate.
Right mate, run it in sensibly, start off quite slow and gradually get quicker. Start with low engine revs and don't labour the engine but gradually make it do more and more work and increase the revs. If you can ride it somewhere where you're going up and down the gearbox (ie peak district in the UK) then that would be ideal. Don't go and sit on a motorway for 500 miles at a uniform speed and uniform load. Doing the same speed won't achieve anything.
The reason I asked which bike is because there are some (like the old fireblades) that end up quicker / better if they were thrashed from new. Good luck mate.
Oh and take it to the Bulldog bash, get your quarter mile time on it.

Answer 4

First 100 miles, no more than 25% throttle, next 200 miles, no more than 50% throttle, next 300 miles, no more than 75% throttle, then ride as normal thereafter.
Vary your speed /revs as much as possible. It is not engine speed which causes poor bedding in, but unsufficient or excessive loading on the components. Varying your revs will ensure that components rubbing in patterns are consistent at all engine speeds.

Answer 5

The engine is taken to full power at the factory before it gets into the frame, so running it in is simple,when you start it don't sit there at idle to warm it up ,drive it , it warms up quicker this way,don't over rev it and you won't have any problems,change the oil at the recommended intervals.

Answer 6

The maker's handbook should tell you the correct procedure for the engine you have. Failing that, a good garage or engine re-builder (look in Yellow Pages) will give you good advice. In general, though:
1. Do not run the engine at high speed from cold, but let it warm up at a good idle speed. 2. Always try to keep the engine at about 30 mph for the first 500 miles, then no more than 40 for the remainder of the running-in period. 3. Keep the engine in the highest gear you can, consistent with it not being under undue strain (e.g going uphill). 4. At the end of the running-in period, use a flushing oil to clean out the engine (there wil be metal fragments -- all new engines shed them), then drain the flushing oil, change the oil filter and refill he engine with its usual oil.
Hope that little lot helps!

Answer 7

Use the rev counter and treat it gently for a while, with just occasional blasts of high power for the first 1500 miles or so and it will repay you in the future.
Make sure you stick to the recommended maintenance programme.

Answer 9

unless u want to pay for tickets, high insurance, jail time...loss of bike.....top speed isnt what u need. if u dont want to listen, find out for urself the hard way. hope u have deep pockets for the fines, u gonna need it.

Answer 10

for the first 500 miles just run it in staying slow under 40 mph then after that if there is no problems oil leaks backfiring then go for it open it up
