CB750 / Re: Primary chain k2
« Last post by archmill on May 27, 2024, 09:42:56 PM »
Pauarc, just re-newed the primary chains and tensioner on a 79 F2. The limit on the F2 is 70mm and mine measured 70mm so new chains and tensioner from CMSNL. after fitting, the measurement was 63mm. I think the limit of 70mm is for all 750 SOHC engines but double check.

There is a service limit on the primary chain according to the service manual. Just measure the slack and then you can decide on splitting the cases or not.

It used to be part of a Suzuki service schedule to swop the plugs 1 to 4 and 2 to 3 to even out the spark erosion wear

How long is a piece of string, it depends on level of thrashing and servicing

How many miles should a chain and tensioner do approximately

Tried and tested by a forum member, hardly unknown!

First, I hope you all enjoy your cheap generic coils of unknown quality and further...

If the coils are connected the wrong way round the bike will run but the HT spark will be reversed so instead of jumping from the centre spark plug tip to earth the spark path is reversed. {...}
To put it simple: in a wasted spark system, one of the two, is already jumping from ground to center electrode, so if the spark of say #1 plug becomes reversed, than the #4 plug will be reversed the other way around, because they are one circuit. For the running of the engine, it makes no difference which of the two fires from ground to center electrode: performance is the same.

My wife has a 2023 Jazz Hybrid ..  complicated yea but does 67 mpg even around town
These days if your family car doesn't do at least 50mpg (if you stick to the speed limits) then you either have the wrong car or want to waste money. So actually petrol cost in miles per £ is cheaper than ever.
A pity the cheap electric cars look like they will not be available so as to protect western manufacturing which is lagging behind. T introduced a 25% tax and now B has upped it to 100% in the US on Chinese imports. Expect protection here also.
Renault Zoe is very old technology.
