Inlet rubber3bn/3et

Slightly of topic but the same part of the engine, is the gasket on the inlet a rubber one? There’s a rubber one on mine and it has an air leak, I remember on my other engine it was the cereal box type

@ricky0115 It should be a paper type, quite common for these to let air in here when botched.

@calum god damn, the bike should run without the choke when I get that replaced then. Fingers crossed! Cheers

@ricky0115 Use Athena, or OEM gaskets only.

You can get some paper gasket adhesive to just ensure it's properly sealed. It's what I've used on my engines.

@calum where’s the best place to get Athena gaskets? I remember pricing up OEM on Fowler’s for the top end was like £40 for 2 gaskets

Just received set for the 89 bike, ordered via ebay, £20 something, used before on the 88, athena the way to go

@oldman cheers mate!

@ricky0115 For gaskets and obtaining authentic genuine athena gaskets. Choose none other than PJME.

But personal preference. I use eBay for almost everything else.

[ricky0115]

@calum thanks, also which adhesive would you recommend?

@ricky0115 https://www.pjme.co.uk/acatalog/Yamaha_DT125R_Tools___Workshop_Equipment_.html

Loctite Adhesive Spray.

Bought that like 5 years ago and still use it today.

People will no doubt say it's unnecessary. All I can say is I've only built engines with it and never had any problems. But I'll admit it's potentially over cautious.

@calum it was made for a reason why not use it! Especially on that annoying gasket on top of the carb

@ricky0115 don’t use rtv silicone it ends up in your reed cage
