hi all can some one addvice me. i have a 199A ive got a new plastic tank when i put it on it dosant seem to sit right at the back where the seat gose. its not siting behind the air box bolt theres a plastic bit pocking out dont know weather it should be there. its only abit out anybody com across this?

sponge under back?

original seat was made for ally tank in the uk

Think you will find Bultaco UK , i have no connection with this company before anybody deletes this post, do a seat for the alloy tank and a seat to suit the plastic tank as the front is a different angle as ND has intimated above.

it not the origanl seat its for a plastic tank from bultaco uk. its not the seat that the problem its the tank witch is not Quit forward enough to alow the seat to push under the spacer on the air box. i think its the tank rest hat the back there to bulky. i do have some thinner ones ill try them first i have an origanl seat on my other bike but thats got a fibreglass tank. witch works well.

you should start with no sponge under tank and fill from there.

this keeps the seat tight in place.

should the seat go between the spacer Aand Airbox?

Lay the tank on the bike and fit front bolt,m8. (no packing sponge under rear of tank)

Push seat forwards pressing down at front so forks of seat fit under frame.

Repeat adding foam till fit is right
