    Clutch Brake Chinese hidraulic opinion

    Yes you are right but I have seen this on a Gsxr after a master cylinder recall where the ASV lever that worked previously caused the same & cooked the discs. I guess the differences must be very small so care is needed regardless of the origin of the part.

    Clutch Brake Chinese hidraulic opinion

    I wouldn't trust Chinese safety critical hydraulic parts. Not worth the risk. Brake levers though are a different deal. Standard levers are made from cast alloy whereas the Chinese CNC levers are made from bar or plate allegedly 6061. It's unlikely that it would be possible to load the lever enough to break it when braking. I have been using Chinese CNC levers for a very long time without any issues.

    EFE Starter keeps shearing bolts

    Think you mean retarding the timing. Advance will make it kick back more

    GS1000G - EFI conversion

    Whatever you do don't follow any of the advice on the GS resources link. The guy who attempted it was oblivious to his lack of skill & reluctant to listen to advice & he ultimately failed. It is a prime example of what not to do. Arttu was a great help to me when I did my kat.

    GSX 1100 F EFI

    Couple of questions Is the spacing between the pairs of throttle bodies ok for your engine. Will they fit your inlet rubbers

    K&N filters for flatslides

    Oiled filters in the rain are pretty much the same whether they are foam or cotton. Neither are as good as an o.e. filter tucked away in an airbox but it's all about compromises.

    K&N filters for flatslides

    I have done similar but I used the rubbers with Ramair foam filter socks over them rather than k & n's. As has been said the solid end of the k & n seems to cause some sort resonance which messes with fueling. Will be interesting to see what happens if you compare this to how it runs with just the rubber trumpet & no k & n.

    Rs38 flat sides vs standard 1200 mk1 carbs

    Throttle bodies for me. Light throttle & easy to tune. Previously the motor felt better on 34mm Amals than rs38s

    Katana Anti-Dive

    When Kat's were raced back in the day the antidive was usually disabled or disconnected as it compromised the already crap brakes & could cause instability.

    GSXR 1100 STOLEN

    You can always put an extra photo in the listing with a sign on the bike with your email & phone number. Bit late now I know but handy in the future.

    K&N filters for flatslides

    Ramair regeneration kit (their words) arrived today. Expensive for what you get. The cleaner is some sort of detergent. They say it can be reused. The oil is very thin & not sticky like normal filter oil. Doesn't smell strongly of solvent but does dry quickly on the hands to leave an oily residue, not tacky but you know it's there. When it's in the bottle it has the viscosity of fresh milk. No thicker. The instructions say for general road use, filters only need a very light coating of oil, over oiling can cause restriction to the filters use. The pipercross oil kit I have looks to be better as it's 2 X aerosols though again only small 100ml, but make application easier. Just dust on a light coat & let it soak in. The oil viscosity & tackyness seem about the same. See pics for what you get from Ramair.

    K&N filters for flatslides

    I called Ramair today & spoke to a helpful lady. Motorcycle filters do not come ready oiled. The stuff they use leaves a sticky residue so you would notice if it was on there apparently. The sheets of foam they sell are not oiled either. Interestingly she said you don't have to oil the filter. It depends on how exposed the filter is & the environment it is used in. For an old skool bike with the filters where they are, I guess dry would be fine unless you live by a beach. For modern bikes with front facing intakes, I guess oiling would be essential. I have ordered a ramair cleaning kit to see what the oil looks like compared to the motorex oil & the pipercross kit I have.

    Ramair sell 300mm square sheets of foam on Eblag. Would seem a shame to cut up the socks you have. Another option is twin air or finna foam. Made in Holland I think.
