Buyers Beware [THATSDAX.COM] BAD ENGINE
DEAR COLLEGES PLEASE CONSIDER IN FUTURE BUYING FROM THATSDAX.COM. I BOUGHT FROM THIS SELLER I DON'T HAVE ANY SUPPORT NOW. IT'S SELLER FAULT, SHE/HE SOLD ME BAD ENGINE WHICH HAD PROBLEM WITH broken screw-thread in body engine (lucky repaired) http://www.motoredbikes.com/showthread.php?t=6479
NOW IT HAS MORE SERIOUS DAMAGE CAUSED BY LOW QUALITY BROKEN PISTON.
I WROTE TO SELLER VERY LONG LETTER TO EXPLAIN SITUATION. I EXPECT SHE/SHE WILL UNDERSTAND BUT LOOKS LIKE SHE/HE ONLY SELL THEM AND DON'T CARE ABOUT CUSTOMERS. I SPENT $330 FOR ALL AND USE IT FOR 4 MONTHS (IN FIRST 3 MONTHS I USED IT FOR 2-5 MILES TRIPS DAILY; IN LAST MONTH I 14 MILES DAILY). THIS IS NOT VERY MUCH. i FEEL DISAPPOINTED AND CHEATED. LOOKS LIKE SELLER SHIP OVERSEAS LOW GRADE PRODUCTS BECAUSE HE/SHE NOT HONOUR WARRANTIES AT ALL.
I RECEIVED ANSWER FROM SELLER:
Greg. We offer no warranty for sales outside the USA. You can go to the website and find the parts you need to get your motor going again. After break in. Go to a synthetic 2 stroke oil . Thanks.
WHAT MEAN THIS ANSWER? THIS PERSON WROTE TO ME 40 WORDS WITHOUT WORD 'SORRY'. I THINK THIS IS THE MOST CYNICAL ANSWER I EVER READ (SHE/HE FORGOT TO AD 'ENJOY THE RIDE' - UNFORTUNATELY HERE IS NOTHING TO ENJOY NOW). LOOKS LIKE SELLER AGREE IN OPINION THAT ENGINES ARE LOW QUALITY - SILENT MEAN YES. IF SOMEBODY SELL OUTSIDE USA AND NOT HONOUR WARRANTY IT IS MEAN HE/SHE SELL AND SEND RUBBISH.
PART 'You can go to the website and find the parts you need to get your motor going again.' JUST SHOOT ME. HE/SHE WANTS MORE MONEY FROM ME. I SPENT ALREADY $200 FOR KIT I EXPECT QUALITY AND RELIABILITY. SELLER DOESN'T HAVE TO LIKE ME, HE/SHE HAVE TO SELL GOOD PRODUCT.
PLEASE HELP - SELLER CAN'T HELP ME BECAUSE HE/SHE DON'T CARE ABOUT OWN PRODUCT.

Dear Sir/Madam,
My name is Gregory and I bought engine from You at 07-Jun-07 22:00:37 (330126395499). I was happy user until yesterday. Since June, I didn't have serious problems with it. It was very useful engine with small 2-stroke issues. To be honest, I replace some of parts include: kill button, clutch lever, fuel pipe, spark plug, spark plug wire, intake gasket, nuts on steel A2, threaded rods on steel A2 as well. I was mainly happy from its work culture (I had to start it use little high revs; otherwise after 10 min I could use it more sensitive and delicate). I had been able to kill engine with choke, so I didn't have air leak.
I had problem with it which "look" serious but it's wasn't. You can/could read about it at motorized bicycle forum. I repaired it with success by Recoil® Kit. I didn't have problem with engine until today.

Like I wrote above I was happy user. Yesterday I try to ride and I had problem to start it. I didn't have problems day before. At last month I started to work for RWE NPOWER which is 7,5 mile far from me. I used bike only to ride to work and back, 5 days a week. I didn't had problems at all with it (I changed spark plug for original 2 weeks ago and it's surprised me - engine gets some extra power).
Like I wrote already, I tried to ride on Saturday without success. Engine was dead already. I suppose piston moved in cylinder. I rode a little and I hear little "aluminium" "crack" and I had to come back home. I removed upper nuts from cylinder head; I didn't find anything broken for first look. In closer look I found missing chip off piece of piston. I'm sure piston wasn't sealed with cylinder, rather locked by piece of piston. I removed it with little resistance but without tools. Piston is broken on left side, it's look like "rock hit by hammer" It's 1 mm deep crater with smashed left side (with blocked 1 ring on this side). Cylinder looks untouched. Parts of cylinder lock wheels under as well. After that piston rod broke copper bushing under piston. I think some metal base parts changed places (I found some bigger metal parts).
I have to confess I'm not qualified mechanic. I have some experience since I had few months this engine, I study diagrams of it and I know how it works, that's all.
To being honest I don't understand situation, I don't understand why it is broken. I can't find my fault at all. Main fault of this engine is obvious - material from which is engine made is weak. I understand this situation might be able to happen after 1500 - 2000 miles but not after light use in 3 months and 1 month regular use 16 miles daily.
Dear Sir, I remember you have "30 day love it or get your money back Guarantee". I wouldn't like to disappoint you but 30 days are relatively short time to test these engines. I think most breakages happened after between 4-8 months when your customer's habit to ride and pistons of Yours engines are used and might be damaged as well with screw-thread in body engine. In mine opinion both situations are connected each other. I don't want to disappoint you once again but I think you sold me low quality product. From the start cylinder head wasn't proper connected to cylinder body. Cylinder didn't knock. Two last weeks rode very good and smoked from first move. Nothing prognoses this catastrophe. Actually I feel disappointed and little depressed because this situation waste my time spend on this project with spent Ł160 ($320) as well. I just to like my hobby - believe me or not I didn't spent time to tight nuts (except intake, outtake and head cylinder sometimes). This is sad that you sell products with unknown quality. I used 2-stroke oil in ratio 20-25:1, temperature is quite cold outside, so here is not problem with cooling.
There is one thing which is interesting in broken piston. It doesn't have chrome on its surface at all. On your website pictures, Sir, pistons looks shiny but on my pictures they are rather mat. Actually when I touch I feel raw aluminum surface and its typical kettle aluminum - fragile and grey color. Maybe that's why part of aluminum chip broke engine. I think it's understandable - It shouldn't be installed in place where exist detonation. For a proof cylinder is still shine inside.
Unfortunately I disagree with you about warranty. I think your 30 day love it or get your money back Guarantee is something which exist in big corporation networks. This is 30 days to test product more visual and test drive and it is impossible to find material breakage. Engine which will be broken after month shouldn't be sold as well like engine which parts are used after 2, 5 and even 9 months. I didn't have ability to use your product for 30 miles daily from start and replace it in Guarantee time. I mount engine proper. I think mechanical Guarantee is one year like any other new product around the world.
I would like to thank you to have a possibility to use your product. Unfortunately engine which you sent me had fault. This fault was caused by bad quality piston. My engine is broken now. Please help me with replace/money back under warranty.
With regards,
Gregory S.
