OssaClark Posted October 17 Report Share Posted October 17 I think I'm the proud new owner of a 2015 TR 300i.... but it won't start sometimes. The bike came with a 9v battery. I was instructed to push the button prior to kicking. Didn't take long to realize the 9v doesn't activate the fuel pump so I put a little 12v in. Pump runs and logs 21 psi - max. Just kicking the bike I can get to 21 psi after 3 kicks. Right..... what's the pressure with the engine running ? Don't know - the barb off the fuel injector housing broke while I was carefully trying to disconnect the fuel line to check pressure. Two questions... Anyone know where I can get the replacement housing with the barb and 2). Has anyone defined a minimum amount of pressure to ensure the injector is working properly ? I can drop a few drops of premix down the spark plug hole or throttle body and she fires right up. Runs perfectly once it starts. Lots of great information here and kudos to Konrad on his website !

konrad Posted October 17 Report Share Posted October 17 https://www.ossa-efi.com/home/electrics/fuel-injector/fuel-injection-pressure Suggest you download all the factory documentation here: https://www.ossa-efi.com/home/factory-documentation Try searching for the barb by part number.

lotus54 Posted October 27 Report Share Posted October 27 I measured 50 psi with fuel pump running. I have not measured current draw, but that can be very handy to see if fuel filter is plugged. Unfortunately, engine has to come out to replace filter (wish they would have made an access panel, but I understand difficulty in that). Several places still have that cap- did you try Lewisport in the States? (I have a spare, but want to keep it as a spare) Quote Link to comment Share on other sites More sharing options...
OssaClark Posted October 28 Author Report Share Posted October 28 Hi Thanks for the feedback. Yes, I got the part. Lewisports is where I got the bike and he's only 30km away. He's closed Fri - Sun and I just figured he didn't have this part. He did, plus the a new fuel pump and 90° fuel connector in aluminum. I appreciate the 50psi comment. I was maxed out at 21 with a 12v battery and kick starting. Pain the a*** taking the motor out and then back in. I'm just wrapping up the last bits and then I can see if the hard - nearly impossible start problem is behind me. It will be interesting to see running pressure vs static (battery) pressure.

lotus54 Posted October 28 Report Share Posted October 28 The twists and turns are tricky for the engine for certain. Another option for something that needs to be serviced would have been nice. At least the engine complete only weighs 36 lbs. The cylinder can come off with engine in frame (I just did one)- but not super fun. The piston pin needs to be removed, taking piston and cylinder out together. Of course radiator, throttle body and airbox have to come out too. But those are pretty easy. I installed a small 12v Li battery with a momentary button. My ‘super easy start’. Any time the button is pushed the fuel pump will run. Makes it a LOT easier to start. Plus good for priming if you run out of fuel, or trailside troubleshooting. I have had it on all my modern OSSAs. Quote Link to comment Share on other sites More sharing options...
OssaClark Posted October 29 Author Report Share Posted October 29 Good to hear ! Yes, I have a little 12v battery pack hooked up now as well. There was a 9v that came on the bike but didn't take long to realize it does nothing. Need to finish it up and try to start it. Almost a hard enduro scenario on my Beta yesterday.... I'm whooped ! I seen you have a couple of Explorer's. Never heard of that model until 2 months ago - Lewisport brought in one Explorer and 2 TRi's from a recent widow that needed to clear out her garage. I'm not sure if they sold more that 5-10 Explorers in the US. How does the pump work ? Mine will run briefly every time I press the button but quickly shuts off - like max pressure was achieved. Is that regulator of some type that is on the plug side as opposed to the pump side.... Thanks ! Quote Link to comment Share on other sites More sharing options...
lotus54 Posted October 29 Report Share Posted October 29 Yes, they pump runs just a few seconds- once pressure is up it stops. The 9V will ‘wake up’ the ECU, so easier to start, but I think one that will make the pump run makes it a lot easier. I have two Explorers right now, and I bought one new (sold later). I have a 2012 in the shop now doing a piston/cylinder plate and know of one other around. I think quite a few more than 10. I will see the old importer in a week or so, I will try to remember and ask if he can guess how many he brought in. Quote Link to comment Share on other sites More sharing options...

I just seem to like the ‘oddball’ bikes. I have more to add to signature, but can’t remember where to change it and could not find it in a couple minutes.
