There's also the Thunder bike class with Bemsee loads of mods allowed as long as you stay in your power to weight ratio, what class have you been running in?

Probably best to contact the eligibility officer for the class you want to race in, I know your required to complete a eligibility form (around £55 for non members) and as I understand it, no eligibility certificate no racing they don't like post cut off date mods like late model brakes & forks.

a ha bit of the old skullduggery at play

How do you determine your et?

that sound like a crack, may come up & take a looky looky over Easter weekend, have a good season

ah so the part numbers include color codes

what do you get 2 qualifying run's then onto eliminations?

@et1170what are the entry fees to race in the et class at santa pod these days?

great info cheers seems part no's are different between 750 & 1100

Anyone know if 88/89 gsxr 750 & 1100 share the same belly pan fairing ? I know the 750 & 1100 top & middle fairings are not shared between the two models but are unsure about the lower one...

amazing what you can find on oss with a little digging around, just what I was looking for

I do have the airbox off at the min?

she's a bit spluttery, going to check if the Ignition rotor is clean?

I thought the same about battery, hooked up to a big boy on jump leads, spark still weak, like you said at least I have a spark...

Morning all, getting a lazy spark 92wn (not a big fat bang of a spark) any ideas? checked wires all ok, good earth, plugs all good, plug caps all good.. im stumped can coils loose their punch over time, or could it be because the old girl's been sitting for a wile?

yes you'd think it would be simple.... still thinking about it the stock set up should be more than capable like you say it's just about recalibrating the brain

I think you correct in saying that, so what I am planning to do is run two front ends stock for CRMC & Modified for Bemsee & FPR/NGRR or if I can get on with the stock brakes then I will stick with the stock set up.
