Has anybody installed the Twin Motorcycles flanges? Just curious of what you think of them | ||

I don't get what the problem is with the stock flanges. I've never had an issue with them not sealing properly. as long as the mating surface are clean and you get the allen bolts tight, they should work perfect. | ||

plus one for never having an issue with the stock ones... and I've done many.. Clean surfaces and O-ring lube or rubber grease applied to the rubber, use your fingers and smear it over the whole seal. The only stock ones to give me grief were when HD changed to the composite ones... I lost count of how many of them we changes under warranty.. | ||

When a bike is running poorly, that's the first thing people say to check. So either bad intake seals are common, or it is a common misconception that they go bad. | ||
| Stev0 |
it's a common missconception in my experience... in the same way that almost everyone says do the TPS reset for every tuning issue. | ||

Well I am certain that my seals are leaking, and isn't TPS only for fuel injection? I have a "02" M2 carbureted bike. | ||

 $5300 worth of handy work from H/D Buell authorised mechanic. Intake seal and header seal. Strathpine wankers. | ||

How on earth can some idiot do that ?????? Mind you I started to see that at the dealership.... They were getting the sales guys to fit accessories and started to class big bore kits as such.... I left about then. I also had two 95 cube kits come through my own shop within a month or so, one was done in Cairns and the other in Melbourne.. Both had the all the oil ring gaps lined up... and of course excessive wear on the edges of the scraper rings. | ||

"AND" a lot more BAD things are done at STEALERSHIPS ... That is why "i" am only one that touches my 1997 S3T !!! That is one of the reasons the TOP-END has never been off my engine !!! | ||

The only issue with the stock set up is if someone does not get the bolts tightened propey they will loosen thus creating the issue. | ||
| Buellistic |
When "i" had to change my INTAKE SEALS, my UP-DATE was to HEX HEAD BOLTS that could be SAFETY WIRED ... The next UP-DATE was to put the BUELL FAN KIT on ... This way the intake manifold bolts stay TIGHT and the seals last much LONGER ... | ||
| Jayvee |
I thought the seals had to be replaced every 5-10 years because the rubber would age, heat cycle, dry out, whatever. Does that make it a poor design? Or a "consumable" like tires? I also put hex bolts on the outside, like Buellistic said, by the way. | ||

According to the Mikuni HSR tuning manual, the stock manifold is good for the vast majority of streetable, high performance HD engines. Here's an excerpt: Which Manifold? The great majority of HSR installations use the stock intake manifold that has been fitted to all Big Twins and Sportsters for more than 20 years. This manifold is an excellent performer. It is reliable, has excellent airflow and is available. We recommend its use. However, Should you choose to fit a Mikuni HSR45 or 48, you must fit a manifold other than the stock one. Also, if your engine has larger ports (the large S&S motors for example) or the heads have a non-standard spacing (many S&S strokers or some other clone engine designs), then you must fit a non-standard manifold. Mikuni produces an alternate manifold design. Our manifold's two piece construction allows us fit different rubber flanges that accept 42, 45 or 48 millimeter HSR carburetors.} |
