Daytona 675 or street triple cams

Hi all I wonder if you could help me.

I have inherited a 2010 Daytona 675 engine and it is a shocker to start. The usual trouble shooting has occurred to rectify the problem (the list is long) yet I still haven't solved it.

When I had the cam cover of I took a photo of the cams and had a quick search to see if they were Daytona 675 or street triple cams. The photos are of my bike and a file photo of a street triple. They have the same cam numbers Inlet 261, Ex 26E which I am concerned about.

Can a clever person confirm that they are street triple cams in my bike (or not) and if so could this be the cause of my starting problem?

Thanks very much.

Someone has definitely done something with the cams. The gears are not the stock ones that came on the engine. Those look to be adjustable and could very well be the source of your problems. The marking on the cams are probably 26i and 26e (intake/exhaust). I doubt the shafts themselves have been replaced but the gears are unlike any stock ones I've seen. From the pics they don't have the lines on them for timing the engine to the crank.

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

Are there machined slots on the opposite end of the cams?


Here are some pics of what I am talking about:

Thanks for your help all

It looks like the cams in my engine do not match the race cam code numbers.

The cams only match the code numbers of the street triple and have the factory adjustable cam sprockets from the street triple, as the race kit sprockets are market so line up intake and exhaust cam sprockets.

It look like I have 2014 Street Triple cams in my engines. If anyone had some good condition Daytona 675 cams in and ex please contact me.

Are you sure you don't have an entire ST engine, and not just the cams?

If you buy Daytona cams, I would also make sure that they come with the matching lifter buckets (engine position labeled). During break-in, the cam lobes and buckets develop a wear pattern. Mix-and-matching cam lobes and buckets after break-in will cause excessive wear. You might be able to have your Daytona cam and buckets machined and break them in again, but that is less ideal as you are taking more material off.

That's a good question and I think we can now rule that out.

Ideally yes, but others have switched cams without issue. You could have the buckets WPC treated which may help. I am actually doing that to my current build. Untreated left, treated right.
