I have been using fuel tubing O rings for over a year now (because of the crappy brown factory ones like you described). The tubing is a perfect fit, is fuel resistant, nice and slippery so the needles turn easily but still stay in place, and it doesn't dry up and go flaky. The perfect material for the job. Works a treat.
Did you fit the bigger or smaller O rings in Marks kit ?

the ones i got in the kit were all the same size ...

you pot the feul tube on the hsp and lsp ?

hmmm yeah great minds think a like matt, already got back with the heat gun. Although they dont have $15 ones cheapest was $50 Ryobi one, so it should last a while...... hopefully. Better this way, wont get in shit for getn nitro and grease all over the gf's hair drier

gonna take a couple pics (with m3's on just for spyke) then start her up.

RAGE

Walked outside with the car.... plugged in the heat gun..... it started raining..........

Arghhhhh - I sympathise with you bro. Darn weather is a pain in the butt.
Good move on the heat gun too. Keeps the little lady happy (most important) and works much better too. You need to heat those puppies up real good when their brand new to get them spinning over easily.

We want video with sound of the mighty 7 roaring into life

oooooooooo name brand heat gun very nice ......

yea good call dont mess with ladies it just aint worth the heart ache .....
they are patient enough at times with our obsesive hobby

i feel your pain i rn a motor in and the weather was awful rain and so on mut i done it anyway couldnt resist going back to work knowing i hadnt done it yet

Hmm - OK I got two different sizes

Yep, check out a post I just put up on the fuel tube O rings on the other GO forum, It's easy to do and very effective. Like I say, I have been running the same fuel tube O rings for just on a year now, no problems at all. I just didn't want to put the same flakey factory O rings back in, and Marks nitrile ones were not available at the time, so neccessity was the mother of invention

good call one always has fuel tube laying about and never o-rings ....

one o-ring i also want to replace is the 15.2x1.5 the carby oring that goes in the crank case mark has none in stock i will have to call him and then go searching for this size seems hard to get ...

Well i managed to get 2 tanks through it.
sounds awesome.

man that engine was tight though..... starter box (which has the one big motor) was struggling to kick it over even when i had the engine warmed to 100 - 120c.

looking forward to getting some more tanks through her tomorrow.

oh yeah and the steering on the rc8b..... wow. and i havent even got it at full throw yet bloody glad i spent the money and went with the hitec 7955

i ran a 7 port at our State Titles the other month in my rc8 and it was off its head lol

and your right the rc8's could turn up their own backsides they've got so much steering lol.

i had to turn the end point right down at 1st and only gradually dialed it up again however im still only around 87%.

Mike

Possibly, we've both been at Castlemaine racing some days

Hmmm lol. Fair enough, was just curious as you used my first name... or did you get that from another post i made?

dam school holidays..... worst timing for the new motor run in. The bmx track and skate park will be packed during the day and its a good place for the run in to. Dont have anyone crying about the noise i forgot how loud they are...... even on idle that 7 port is so frickin loud.

Hi Guys
I thought I better give you guys the heads up on the new ceramic bearings from Massive Mark.Not only is his service second to none and a gentleman at that, but he fitted the bearings up for me, but before he did I had to have a feel(of the ceramics that is) and talk about bloody smooth,just bloodly beautiful.He also check my motor out for me and said that all was good but replaced the rod and gungen as well as I thought while its apart.why not.Anyway a long story short,put motor back and the thing purrs like a kitten but turned into a tiger,Those bearing are great!A must for all go engines.
Mark, Your the man

Cheers crashman, I was wondering what those Answer bearings were like. Thanks for the feedback man. Oh dear - another thing to add to the shopping list (read that as wish list)
