Need valve clearance spec for 2011-2012 675R

Yes, this seems like a stupid question as you'd expect this info would be readily available/straight-forward...but its not. :)

I have a factory service manual, part # 3856750 published in June 2009. According to this manual, the specs are as follows:
For Daytona up to VIN 381274: Ex 0.275-0.325
For Daytona from VIN 381275: Ex 0.325-0.375
Screenshot from the manual:


My 2011 675R VIN is 485548, so would be the latter (0.325-375).

However, I'm finding conflicting info regarding the spec:
This manual makes no specific reference to a 675R...just the 675, Street Triple, and Street Triple R. Also no mention or pictures of oval exh ports, slipper clutch, etc...which makes me wonder if this manual is applicable. The only other service manual I can find is for the 2013+.

There are multiple posts on this forum (including posts in the VC sticky post) which state the VIN number ranges reversed. See THIS post as an example. (e.g. VIN <=381274 as 0.325-0.375mm, VIN >=381275 as 0.275-0.325mm)
Soooo...can anyone help clarify? My exh clearances are 0.279. So either i'm on the tight side or way out of spec. I'll be going by my manual otherwise which means I'm nearly 0.1mm out of spec (ouch). I'm wondering if the previous owner was also confused and maybe set it to the wrong spec. If the specs are wrong in that sticky thread, then possibly other owners may be doing the same thing.

The manual you have was published in 2009 and the R didn't come out until 2011, so that explains that.

The specs for a 2006-2008 are IN 0.10-0.20 and EX 0.275-0.325.

I don't have a 2009-2012 service manual, but I know 2013+ specs are IN 0.10-0.20 and EX 0.325-0.375. Your screenshot would suggest those looser specs started in 2009 with the updated motor.

There's no reason to believe Triumph would have the tighter clearances in 06-08, go looser for a little bit then go back to tighter, only to go looser again in 2013. The reversed VIN ranges is a typo. Your specs must be the same as 13+, so IN 0.10-0.20 and EX 0.325-0.375.Your exhaust clearances are too tight. The previous owner was probably going off an 06-08 service manual, which is easily found for free online.

To add to MGF's post, there are no engine differences between the R and non-R models. The specs are the same.

The sooner you introduce motorcycles into your children's lives, the less likely they'll have money for drugs, alcohol and cigarettes as teenagers.

Yep, understood that the R didn't come out until 2011.

I also thought the same thing as far as being illogical to alternate between tighter and looser EX specs through the years. But you never know. It doesn't help that there isn't any FSM which directly references the 675R until the 2013+ FSM came out. As far as I can find: there have only been 2 FSMs. I cannot find a FSM part number between the June 2009 version and p/n 3856909 which came out on Nov 2012 and is for VIN 564948+ (the 2013 generation)

If nothing else: the VIN # range typos on the site could have mess some folks up. Wonder if it started from a bad 3rd-party manual.

Like the folks above said, once they were loosened, they stayed loose from that vin onwards and r engine is identical to non r engine. Shots below from official d675 and Hayes manuals.

Attached is my 2014 Manual and it covers them all; R, non-R, and the Street Triples. No difference in adjustments, except of course the differences between Intake and Exhaust which are 0.10 - 0.20 mm and .325 - .375 mm respectively.

Thanks for the extra confirmations. Yes, I kind of figured that's the case - its the posts in the other thread that raised some doubt as well as the early FSM from triumph not specifically addressing the 2011/12 "R" models.

Had to order a few Triumph half-size shims; +/- 0.05mm for the exhaust is relatively small. I happen to be exactly halfway between normal shim increments on a bunch of valves.

Totally normal to be between increments. If you don't have your own set of shims, usually a dealer will have a big pile of them in each size range. Measure them with some calipers and many of them won't actually measure what's stamped on them. I find they're typically off by 0.01 mm. I was able to get exactly to the range I wanted by trading with my dealer and finding some in-between sizes that otherwise would've been special order.

Do you know if anyone offers sets of these half-size shims? I have a full set from Hot Cams but as noted: they are 0.05 increments because this covers almost all bikes. Seems you can only buy them 1 at a time. Would be nice if you could buy a range of half-sizes for a reasonable price. Unfortunately I couldn't find a single shop within a 50+ mile radius which had anything on-hand.

I was half-joking with a friend of mine that this is a good excuse to buy a surface grinder. :)
