i seem to be aking dumb questiuns on a daily basis but if you're not sure just ask.
so i'm intending to start putting things together this weekend. think ive got it sussed with a lot of advice but theres just one more thing i'd forgotten about.
theres a 2 into 1 exhaust on the bike but its loose (to my mind) in the heads. theres no gaskets shown in the drawings and i've been advised that exhaust cement/paste shouldn't be used but no reason why
the joint in the exhaust down by the right engine mount looks like theres just a clamp to hold the two bits tightly
what is the recommended way of making them airtight? or doesn't it matter
Let's answer your last 4 words 1st.
Yes it matters, as airless will give you popping and banging in the exhaust on the overnight.
Simple fix , I use clear bathroom silicone sealer smeared around the pipes where I push into the head.
Seems to work a treat and surprisingly resilient.
Makes a seal until the carbon builds up
i would have thought myself that they would need to be sealed but the advice i had was the opposite.
i was told to brace exhausts so they were being forced back into the heads and that would suffice. exhaust assembly paste would be my choice
im sorry , just re-read my reply
AIRLESS should have read AIRLEAKS do matter
and OVERNIGHT should read OVERRUN
silicone works fine for me
I have tried gun gum or suchlike , but it can build up crusty lumps which can prevent sealing if left in there when you do any dismantling in the future
got the jist of it mate. i have to re read what i've written three times to make sure my drugs are working
Ordinary bathroom silicone for me too - works much better than the expensive high temperature stuff.
I have at least four tubes of expensive exhaust sealant none of them work any better than a tube of silicone from the builders merchants.
looks like it'll be silicone then. might use bathroom stuff then it'll be waterproog in the rain
any particular one? or just any
I just used the cheapest at my local builders merchants last year it cost me about £2.50 iirc.
proper job £1.95
they sell joint paste foe £2.99 which is what i was going to buy
